description The asymmetric unit of title compound, C20H23ClN2O, consists of two crystallographically independent molecules (A and B) in which the orientations of the 4-isobutylphenyl units are different. The isobutyl group of molecule B is disordered over two positions with occupancies of 0.850 (5) and 0.150 (5). The dihedral angle between the two benzene rings is 88.70 (9)° in molecule A and 89.38 (9)° in molecule B. The independent molecules are linked together into chains along [100] by N—H...O and C—H...O hydrogen bonds, and by C—H...π interactions. In the chain, N—H...O and C—H...O hydrogen bonds generate R21(6) ring motifs. In addition, C—H...N hydrogen bonds are observed. The presence of pseudosymmetry in the structure suggests the higher symmetry space group Pbca but attempts to refine the structure in this space group resulted in high R (0.119) and wR (0.296) values.
