(Received 1 June 2009; accepted 3 June 2009; online 6 June 2009)

In the title compound, C24H39NO2·H2O, the A and C rings of the pregnolene derivative sterol adopt chair conformations, with the B ring in a flattened chair conformation and the five-membered ring in an envelope conformation twisted about the C/D ring junction. The N-tert-butyl­carboxamide substituent is equatorial. The 3β-hydr­oxy H atom and one H atom of the water mol­ecule are disordered over two positions with equal occupancies. In the crystal structure, O—H⋯O hydrogen bonds between the 3β-hydr­oxy groups of neighbouring mol­ecules form dimers in the bc plane and these dimers are stacked along the a axis by additional O—H⋯O hydrogen bonds involving the water mol­ecules. The steric effect of the bulky tert-butyl substituent in the carboxamide chain precludes hydrogen-bond formation by the N—H group.

Comment top

Finasteride, systematic name N-(tert-butyl)-3-oxo-4-aza-5-androst-1-ene-17-carboxamide, is an azasteroid used in the treatment of both Benign Prostatic Hypertrophy and hair loss in the male adults (Rasmusson et al., 1984,1986; Rasmusson & Reynold, 1985; US National Library of Medicine and National Institutes of Health, 2008). The title compound, (I), Fig. 1, is a derivative of pregnenolone (Finar, 1959) which crystallizes with a solvent water molecule and is a key intermediate in the synthesis of finasteride (Li et al., 2001).

The A and C rings of the steroid skeleton (C1—C5, C10 and C8,C9,C11—C14) have chair conformations (Cremer & Pople, 1975) with atoms C3 and C10 - 0.668 (5) and 0.604 (5) Å from the C1,C2,C4,C5 plane (r.m.s. deviation 0.018 Å) and atoms C9 and C13 - 0.601 (4) and 0.701 (4) Å from the C8,C11,C12,C14 plane (r.m.s. deviation 0.011 Å). Ring B (C5—C10) has a flattened chair conformation with an r.m.s. deviation of 0.091 Å from the plane through atoms C5—C7,C9,C10 with atom C8 displaced 0.588 (4) Å from this plane. The five membered ring D (C13—C17) has an envelope conformation twisted about the C/D ring junction with atom C14 - 0.617 (5) Å from the plane through C13,C15—C17 (r.m.s. deviation 0.082 Å).

The close similarity between this molecule and pregnenolone is amply demonstrated by the fact that the structure overlays with that of pregnenolone (Lancaster et al., 2007; refcode PREGOL01 in the Cambridge Structural Database, version 5.30, Feb. 2009; Allen, 2002) with an r.m.s. deviation of 0.111 Å. This deviation drops to 0.045 Å if the carbonyl O2 atom is omitted from the calculation, Fig. 2 (Macrae et al., 2006). The C16—C17—C20—O2 torsion angle which defines the conformation of the carboxamide group with respect to the main skeleton is -26.9 (5) °, significantly greater than the values in the range -3.0 to 0.6 ° reported for pregnenolone itself (Bordner et al., 1978; Lancaster et al., 2007) but more comparable to those found in pregnenolone derivatives with substituents elsewhere on the steroid backbone (Duax et al., 1989; Shukla et al., 2008).

In the crystal structure O1—H1OA···O1 hydrogen bonds form dimers in the bc plane. O1W—H1W···O1W hydrogen bonds link pairs of water molecules, while O1—H1O···O1W and O1W—H2W···O1 interactions stack the dimers along a (Fig. 3). The amide N1—H1 group is not involved in hydrogen bonding interactions, presumably because of the shielding effect of the bulky tert-butyl substituents.

Experimental top

The title compound was prepared from pregnenolone as previously described (Rasmusson et al., 1984; Dolling et al., 1999). A single-crystal of the title compound, suitable for X-ray analysis, was grown by slow evaporation of the solvent DMF/H2O (1:2 v:v).

Refinement top

The H atoms bound to C were positioned geometrically and constrained to ride on their parent atoms [C—H distances are 0.97–0.98Å for CH2 and CH groups with Uiso(H) = 1.2 Ueq(C), and 0.96 Å for CH3 groups. The O—H and N—H hydrogen atoms were refined with their isotropic displacement parameters 1.2 Ueq(O,N) for the O—H and N—H groups and 1.5 Ueq(O) for the water molecule. Distances were constrained to 0.82 (1) Å for the O—H bond 0.85 (1) Å in the water molecule and 0.90 (1)Å for the N—H bond. The H1O atom on O1 and the H2W atom of the water molecule are each disordered over two positions with equal occupancies. This disorder leads to a close approach of the O1 atoms and their hydrogen atoms on adjacent molecules. The absolute configuration of (I) could not be determined and Friedel equivalents were averaged in the refinement. The chosen configuration was based on that of the pregnenolone precursor with C3 S, C8 R, C9 S, C10 R, C13 S and C14 S.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
