چکیده
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.

In the title compound, C(21)H(25)NO(3)·C(2)H(4)O(2), the piperidone ring adopts a chair conformation. The two meth-oxy groups are nearly coplanar with the aromatic rings to which they are attached. The dihedral angle between the two aromatic rings is 60.9 (2)°. There are two short intra-molecular N-H⋯O contacts. The crystal packing is stabilized by inter-molecular O-H⋯N and C-H⋯O inter-actions.
