Procedure

In substantially the same manner as in Reference Example 47, 5-chloro-2-thiophenecarboxamide was allowed to react with 1,3-dichloroacetone to give 4-chloromethyl-2-(5-chloro-2-thienyl)oxazole. The yield was 51%. Recrystallization from ethyl acetate-hexane gave colorless needles, mp 90-91° C.
