The present invention provides an efficient process for the production of N-acylaniline derivatives by selectively alkylating an amide group at the nitrogen atom. The process comprises reacting an amide compound of the formula (2): (wherein, R1 and R2 are each independently an alkyl group, a substituted alkyl group, an alkenyl group, a substituted alkenyl group, an aryl group or a substituted aryl group) with a sulfuric acid ester in the presence of a solid metal hydroxide to give an N-alkylamide compound of the formula (3): (wherein R3 is an alkyl group and R1 and R2 have each the same meaning as described above).
