5-Acetyl-3-hy-droxy-4-phenyl-4,5-dihydro-1H-1,5-benzodiazepin-2(3H)-one.

ABSTRACT: In the title compound, C(17)H(16)N(2)O(3), the seven-membered diazepine ring adopts a boat conformation with the hy-droxy-substituted C atom at the prow and fused benzene ring C atoms at the stern. The phenyl substituent occupies an equatorial position. The amino group of the ring system is a hydrogen-bond donor to the oxo O atom of an inversion-related mol-ecule, and the hy-droxy group is a hydrogen-bond donor to the acetyl O atom of another inversion-related mol-ecule. The two hydrogen bonds generate a ribbon motif parallel to [10[Formula: see text]] in the crystal structure.
