反应详情

A mixture of 1.0 g of beta-carboline-3-carboxaldehyde, 10 ml of dimethyl-formamide and 3 ml of N,N-dimethyl hydrazine is introduced into a glass autoclave. The air is replaced by nitrogen. After stirring for 3 h, the reaction mixture is allowed to stand overnight at room temperature. After adding 25 ml of water, the reaction mixture is extracted with 100 and 50 ml of chloroform. The chloroform phase is dried using magnesium sulfate, then filtered. Then, the chloroform is evaporated. After adding 10 ml of ether, the reaction product is filtered off. 0.9 g of beta-carboline-3-carboxaldehyde-dimethylhydrazone with a m.p. of 203°-206° C. is obtained.
