2,6-Bis(3-methoxy­phen­yl)-3-methyl­piperidin-4-one

In the mol­ecule of the title compound, C20H23NO3, the bulky methoxy­phenyl substituents at the equatorial 2,6-positions crowd the vicinity of the equatorial amino H atom and prevent it from forming inter­molecular hydrogen bonds. The piperidine ring adopts a distorted chair conformation.
