The conformation of the N-H bond in the structure of the title compound, C(10)H(12)ClNO, is syn to the ortho methyl group, similar to that observed with respect to the meta methyl group in 2-chloro-N-(3-methyl-phen-yl)acetamide and the ortho-chloro group in 2-chloro-N-(2-chloro-phen-yl)acetamide. The geometric parameters are similar to those of other acetanilides. The mol-ecules are linked into chains through inter-molecular N-H⋯O hydrogen bonds.
