The crystal structure of the title compound (26DMPCA), C(10)H(12)ClNO, is closely related to those of side-chain-unsubstituted N-(2,6-dimethyl-phen-yl)acetamide and side-chain-substituted 2,2,2-trichloro-N-(2,6-dimethyl-phen-yl)-acet-amide and N-(2,6-dimethyl-phen-yl)-2,2,2-trimethylacet-amide, with slightly different bond parameters. The mol-ecules in 26DMPCA are linked into chains through N-H⋯O hydrogen bonding.
