Procedure
In substantially the same manner as in Working Example 72, 1-[3-(4-hydroxyphenyl)propyl]imidazole was allowed to react with 2-chloromethyl-5-phenylbenzoxazole to give 2-[4-[3-(1-imidazolyl)propyl]phenoxymethyl]-5-phenylbenzoxazole. The yield was 77%. Recrystallization from ethyl acetate-hexane gave pale yellow plates, mp 123-124° C.
