HCID 7364964-(Chloromethyl)-2-(thiophen-2-yl)-1,3-thiazoleYield 65%

Procedure

In substantially the same manner as in Reference Example 73, 2-(2-thienyl)-4-thiazolylmethanol was allowed to react with thionylchloride to give 4-chloromethyl-2-(2-thienyl)thiazole. The yield was 65%. Recrystallization from ethyl acetate-hexane gave colorless needles, mp 54-55° C.
