Versuchsvorschrift
In substantially the same manner as in Reference Example 31, 4-benzyloxybenzamide was allowed to react with 1,3-dichloroacetone to give 2-(4-benzyloxyphenyl)-4-chloromethyloxazole. The yield was 33%. Recrystallization from ethyl acetate-hexane gave colorless prisms, mp 119-120° C.
