反应详情

A solution of 30 g (0.17 mol) of 1-methylimidazole-4-sulfonyl chloride from Example C-1 in 150 ml of acetonitrile is added dropwise to a solution of 24 ml (0.17 mol) of 3-morpholinopropylamine in 50 ml of acetonitrile (or dichloromethane). The temperature of the reaction mixture is kept at room temperature or below by external cooling with ice-water. Stirring is continued for 6 h at room temperature. The precipitate deposited is filtered off with suction and recrystallized from acetonitrile in order to give 46 g (85% of theory) of the title compound (hydrochloride) of melting point 207°-208° C.
