实验过程

2-Aminonicotinaldehyde (1.5 g, 12.3 mmol) and 2-acetylthiazole (1.64 g, 12.9 mmol) are dissolved in 12 ml of MeOH and the mixture is treated with 1.5 ml of 40% KOH. After 3 h, the reaction is complete and the mixture is poured onto water. The solid which is deposited is filtered off with suction, washed and dried. 1.22 g (yield 46%) of the desired product are obtained. M.p. 160°-165° C.
