Paragraph 0056; 0059, (2017/02/09)
PROBLEM TO BE SOLVED: To provide a method for producing N-alkyl piperazines in high yield by selectively alkylating one amino group.SOLUTION: In the method for producing N-alkyl piperazines, piperazines represented by general formula (1) are reacted with a specific alkylating agent in the presence of an acid. In the formula: R-Rare each independently a hydrogen atom, a methyl group, an ethyl group, a 3-8C linear alkyl group or the like, a hydroxyethyl group, a hydroxypropyl group, a dihydroxypropyl group, a methoxy group, an ethoxy group, a phenyl group, a benzyl group, a 2-phenylethyl group, or the like.
