Procedure
In substantially the same manner as in Working Example 33, 3-[4-[2-[(E)-2-phenylethenyl]-4-oxazolylmethoxy]phenyl]propyl methanesulfonate was allowed to react with tetrazole, and the reaction mixture was subjected to extraction. The extract was subjected to a silica gel column chromatography. From the fraction eluted with ethyl acetate-hexane (1:1, v/v), 2-[3-[4-[2-[(E)-2-phenylethenyl]-4-oxazolylmethoxy]phenyl]propyl]-2H-tetrazole was obtained. The yield was 41%. Recrystallization from ethyl acetate-hexane gave colorless prisms, mp 97-98° C.
