HCID 220098072-(4-Benzoylphenyl)-4-chloromethyloxazoleYield 46%

Procedure

In substantially the same manner as in Reference Example 47, 4-benzoylbenzamide was allowed to react with 1,3-dichloroacetone to give 2-(4-benzoylphenyl)-4-chloromethyloxazole. The yield was 46%. Recrystallization from ethyl acetate-hexane gave colorless prisms, mp 138-139° C.
