Abstract
In the molecule of the title compound, C16H17NO, the N—H and C=O bonds are anti to each other and the two benzene rings form a dihedral angle of 75.8 (1)°. The amide group is twisted by 28.1 (3) and 76.3 (2)° out of the planes of the 4-methylphenyl and 2,4-dimethylphenyl rings, respectively. In the crystal, intermolecular N—H⋯O hydrogen bonds link the molecules into chains running along the c axis. The crystal studied was hemihedrally twinned with a twin law resulting from a twofold rotation about the a axis.
