3,5-Dimethyl-1-{2-[(5-methyl-1,3,4-thia­diazol-2-yl)sulfan­yl]acet­yl}-2,6-diphenylpiperidin-4-one

In the title compound, C₂₄H₂₅N₃O₂S₂, the piperidine ring adopts a distorted boat conformation. The phenyl rings subtend angles of 75.6 (1)° and 86.3 (1)° with the mean plane of the piperidine ring. In the crystal, mol­ecules are linked through a network C—H...N hydrogen bonds, forming zigzag chains along [100]. The thia­diazol ring methyl group is disordered over two positions with an occupancy ratio of 0.69 (4):0.31 (4).
