The conformation of the N-H bond in the title compound (34DMPA), C(10)H(13)NO, is syn to the 3-methyl substituent in the aromatic ring, in contrast to the anti conformation observed with respect to the 3-chloro substituent in N-(3,4-dichloro-phen-yl)acetamide (34DCPA). The asymmetric unit of the structure contains three mol-ecules. The bond parameters in 34DMPA are similar to those in 34DCPA, N-(2,6-dimethyl-phen-yl)acetamide, N-(3,5-dimethyl-phen-yl)acetamide and other acetanilides. The mol-ecules in 34DMPA are linked into infinite chains through N-H⋯O hydrogen bonding.
