N-(2,4-Dimethyl-phen-yl)-4-methyl-benzamide.

In the mol-ecule of the title compound, C(16)H(17)NO, 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-methyl-phenyl and 2,4-dimethyl-phenyl rings, respectively. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules 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.
