(2R,6S)-tert-Butyl 2-(benzhydrylcarbamoyl)-6-methylmorpholine-4-carboxylate

The title compound, C24H30N2O4, was obtained by the reaction of (2R,6S)-4-(tert-butoxycarbonyl)-6-methylmorpholine-2-carboxylic acid with diphenylmethanamine in dimethylformamide solution. The morpholine ring is in a chair conformation. In the crystal, weak intermolecular C—H...O hydrogen bonds link molecules into chains along the b axis.
