title: r-2,c-6-Bis(3-methoxy-phen-yl)-t-3,t-5-dimethyl-piperidin-4-one.
abstract: In the title compound, C(21)H(25)NO(3), the piperidinone ring adopts a chair conformation with an equatorial orientation of all substituents; the 3-methoxy-phenyl groups make a dihedral angle of 60.26 (15)°. The carbonyl group O atom is disordered over two positions in a 0.643 (3):0.357 (3) ratio. The crystal structure is stabilized by N-H⋯O and C-H⋯O hydrogen bonding.
