1-Acetyl-t-3-ethyl-r-2,c-6-bis(4-methoxyphenyl)piperidin-4-one

In the title compound, C23H27NO4, the piperidine ring adopts a distorted boat conformation. The methoxy groups lie in the plane of benzene rings to which they are attached [maximum deviations of 0.014 (3) and 0.007 (3) Å]. The benzene rings are oriented at angles of 67.2 (1) and 87.0 (1)° with respect to the best plane through the four co-planar atoms of the piperidine ring.
