3-{[3-(4-Methoxyphenyl)-4,5-dihydro-1,2-oxazol-5-yl]methyl}-1,5-dimethyl-1H-1,5-benzodiazepine-2,4(3H,5H)-dione

The molecule of the title compound, C22H23N3O4, 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 methylene C atom connected to the methine C atom occupies an equatorial position. The methylene 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 intermolecular C-H center dot center dot center dot O hydrogen bonding is present in the crystal structure.
