The asymmetric unit of the title compound, C
16H
20ClNO
2, contains two molecules in which the dihedral angles between the benzene ring and the plane of the amide unit are 77.4 (1) and 81.1 (1)°. In both molecules, the five-membered ring adopts an envelope conformation with one of the β-C atoms as the flap. In the crystal, molecules are connected
via C—H

O hydrogen bonds, forming chains along the
b-axis direction. These chains are further linked by C—H

π interactions, forming a three-dimensional network.

The title compound, (I) was prepared by a method reported in literature
(Krauss et al., 1995). The crystals were obtained by
dissolving (I) (0.1 g)
in
methanol (30 ml) and evaporating the solvent slowly at room temperature for
about 8 d.
All H atoms were positioned geometrically and constrained to ride on their
parent atoms, with C—H = 0.93 Å for aromatic H, 0.96 Å for alkyl H and
0.97 Å for other H, respectively. The Uiso(H) = xUeq(C),
where x = 1.2 for aromatic H and x = 1.5 for other H.

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. |

The title compound (I) is an important intermediate in the synthesis of [(piperidinoalkanoyl)phenyl]propionates, which can be utilized to synthesize antihistaminics (Krauss et al., 2001).
The molecular structure of (I) is shown in Fig. 1. There is a intermolecular contact C—H···O in the title compound, forming molecular chains (Table 1, Fig. 2). The crystal packing is further controlled by C—H···π interactions [C18—H18B···Cg4 distance of 2.730 Å, C4—H4B···Cg2 distance of 2.890 Å and C23—H23B···Cg2 distance of 2.980 Å (Cg4 and Cg2 are the centroids of the rings defined by the atoms C25—C30 and C9—C14, respectively)].
The dihedral angles between the benzene ring and the plane of the amide are 77.4 (1)° and 81.1 (1)°, respectively. The conformation of 5-memebred rings are both envelope with the tip atoms C3 and C18, respectively.
