3-Hexadecyl-1,5-dimethyl-1H-1,5-benzodiazepine-2,4(3H,5H)-dione

In the title molecule, C27H44N2O2, the seven-membered ring adopts a boat-shaped conformation, with two C atoms of the fused benzene ring forming the stern and the methine C atom forming the prow. The hexadecyl substituent occupies an equatorial position, with the aliphatic chain exhibibiting an extended zigzag conformation.
