3-[(3S)-3-Ethyl-1-methyl-azepan-3-yl]phenyl N-(4-fluoro-phen-yl)carbamate.

ABSTRACT

The asymmetric unit of the title compound, C(22)H(27)FN(2)O(2), a (-)-S-meptazinol derivative, contains two mol-ecules. The azepane ring adopts a similar twist chair form in both mol-ecules, while the dihedral angles between the two benzene rings are 88.17 (14) and 89.93 (14)° in the two mol-ecules. The absolute configuration of the mol-ecule was determined from the synthetic starting material. The crystal structure is stabilized by classical inter-molecular N-H⋯O hydrogen bonds.
