Procedure
In substantially the same manner as in Working Example 8, pyrrole was allowed to react with 3-[4-[2-[(E)-2-phenylethenyl]-4-oxazolylmethoxy]phenyl]propyl methansulfonate to give 2-[(E)-2-phenylethenyl]-4-[4-[3-(1-pyrrolyl)propyl]phenoxymethyl]oxazole. The yield was 57%. Recrystallization from ethyl acetate-hexane gave colorless prisms, mp 108-109° C.
