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).
本发明提供了一种通过选择性地烷基化氮原子上的酰胺基团来生产N-酰苯胺衍生物的高效过程。该过程包括在固体金属羟基的存在下,将式(2)的酰胺化合物(其中,R1和R2分别独立地是烷基、取代烷基、烯基、取代烯基、芳基或取代芳基)与硫酸酯反应,得到式(3)的N-烷基酰胺化合物(其中R3是烷基,R1和R2的含义与上述相同)。
