✦ Synopsis
The piperidine ring of the title molecule, C~20~H~21~Cl~2~NO, is in a chair form. The dihedral angle between the two benzene rings is 52.4 (1)°. The chlorophenyl and isopropyl groups have equatorial orientations. Weak C—H...O and C—H...N intramolecular interactions were found in the crystal structure.
