3-{[3-(4-Meth-oxy-phen-yl)-4,5-dihydro-1,2-oxazol-5-yl]meth-yl}-1,5-dimethyl-1H-1,5-benzodiazepine-2,4(3H,5H)-dione

Abstract

The mol-ecule of the title compound, C(22)H(23)N(3)O(4), features a benzodiazepine fused-ring system whose seven-membered ring adopts a boat-shaped conformation (with the C atoms of the fused-ring as the stern and the methine C atom as the prow). The methyl-ene C atom connected to the methine C atom occupies an equatorial position. The methyl-ene C atom is connected to the five-membered oxazole ring, both of which are disordered over two positions in a 0.634 (4):0.366 (4) ratio. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.
