Procedure

In substantially the same manner as in Reference Example 47, 3-chloro-2-thiophenecarboxamide was allowed to react with 1,3-dichloroacetone to give 4-chloromethyl-2-(3-chloro-2-thienyl)oxazole. The yield was 54%. Recrystallization from ethyl acetate-hexane gave colorless prisms, mp 84-85° C.
