The title compound, C20H20Br2ClN3O3, was synthesized by the condensation reaction of 2-chloro-5-nitrobenzaldehyde with 4-(2-amino-3,5-dibromobenzylamino)cyclohexanol in a methanol solution. There are two independent molecules in the and in one molecule the atoms of the cyclohexane ring are disordered over two sets of sites with refined occupancies of 0.657 (12) and 0.343 (12). The dihedral angle between the two benzene rings is 89.5 (2)° in one molecule and 82.9 (2)° in the other. In the intermolecular N—H⋯O and O—H⋯O hydrogen bonds link the molecules into chains propagating along [01].

2-Chloro-5-nitrobenzaldehyde (1.0 mol, 185.6 mg) and 4-(2-amino-3,5-dibromobenzylamino)cyclohexanol (1.0 mmol, 378.1 mg) were dissolved in a methanol solution (30 ml). The mixture was stirred at room temperature to give a clear colorless solution. Crystals of the title compound were formed by gradual evaporation of the solvent for a week at room temperature.
H atoms were included in calulated positions with, with C–H = 0.93–0.98 Å, N-H = 0.86Å and O-H = 0.84 with Uiso(H) = 1.2Ueq(C,N) or 1.5Ueq(O). The C29-C34 cyclohexyl ring is disordered over two distinct sites, with refined occupancies of 0.657 (12) and 0.343 (12). Bond length restraints were applied to the disorder model using the SADI commmand in SHELXL (Sheldrick, 2008).
Ambroxol, 4-(2-amino-3,5-dibromobenzylamino)cyclohexanol, is an expectorant agent which leads to bronchial secretion due to its mucolytic properties (Felix et al., 2008; Gaida et al., 2005; Lee et al., 2004). Recently, we reported the
of a derivative of Ambroxol (Wang et al., 2009). In this paper, the of the title compound, derived from the condensation reaction of 2-chloro-5-nitrobenzaldehyde with 4-(2-amino-3,5-dibromobenzylamino)cyclohexanol in methanol solution, is reported.There are two independent molecules in the
of the title compound, Fig. 1. The dihedral angle between the two benzene rings is 89.5 (2)° in one molecule and 82.9 (2)° in the other. The cyclohexyl rings adopt chair configurations. All bond lengths are within normal ranges (Allen et al., 1987).For details of the pharmaceutical uses of Ambroxol,

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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. |

Ambroxol, 4-(2-amino-3,5-dibromobenzylamino)cyclohexanol, is an expectorant agent which leads to bronchial secretion due to its mucolytic properties (Felix et al., 2008; Gaida et al., 2005; Lee et al., 2004). Recently, we reported the crystal structure of a derivative of Ambroxol (Wang et al., 2009). In this paper, the crystal structure of the title compound, derived from the condensation reaction of 2-chloro-5-nitrobenzaldehyde with 4-(2-amino-3,5-dibromobenzylamino)cyclohexanol in methanol solution, is reported.
There are two independent molecules in the asymmetric unit of the title compound, Fig. 1. The dihedral angle between the two benzene rings is 89.5 (2)° in one molecule and 82.9 (2)° in the other. The cyclohexyl rings adopt chair configurations. All bond lengths are within normal ranges (Allen et al., 1987).
