Procedure
In substantially the same manner as in Reference Example 47, 5-methoxy-2-thiophenecarboxamide was allowed to react with 1,3-dichloroacetone to give 4-chloromethyl-2-(5-methoxy-2-thienyl)oxazole. The yield was 1.2%. Recrystallization from ethyl acetate-hexane gave colorless prisms, mp 64-65° C.
