(2R,6S)-tert-Butyl 2-(benzhydryl-carbamo-yl)-6-methyl-morpholine-4-carboxyl-ate.

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.
