-
Paragraph 0057, (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.

Hydroboration of 1,4-diallylpiperazine (I) with triethylamine-borane afforded 5,8-diaza-1,9-diboradispirotetradecane (II). 1,4-Diallylpiperazine dihydrochloride reacted with sodium borohydride to give 1,4-diallylpiperazine-diborane (V).Ethanolysis of II furnished 1,4-bis(3-diethoxyborylpropyl)piperazine (IV).The products of hydroboration of I were subjected to hydrolysis with hydrochloric acid and subsequent oxidation with alkaline hydrogen peroxide and the obtained mixtures were analyzed by gas-liquid chromatography and mass spectrometry.
