title: c-3,t-3-Dimethyl-r-2,c-7-diphenyl-1,4-diazepan-5-one.
abstract: In the title compound, C(19)H(22)N(2)O, the diazepine ring adopts a distorted chair conformation. One of the N-H groups forms an inter-molecular N-H⋯O hydrogen bond generating an R(2) (2)(8) graph-set motif. The other N-H group does not form a hydrogen bond.
