title: 7-Chloro-11a-phenyl-2,3,5,10,11,11a-hexa-hydro-1H-pyrrolo[2,1-c][1,4]benzodiazepine-5,11-dione.
abstract: The title compound, C(18)H(15)ClN(2)O(2), is a potential human immunodeficiency virus type-1 (HIV-1) non-nucleoside reverse transcriptase inhibitor. The pyrrolidine ring adopts an envelope and the diazepine ring a boat conformation. In the crystal structure, two isomers (R and S) form centrosymmetric dimers via N-H⋯O hydrogen bonds.
