3-[4-[2-[(E)-2-phenylethenyl]-4-oxazolylmethoxy]phenyl]propyl methanesulfonate → 2-[3-[4-[2-[(E)-2-phenylethenyl]-4-oxazolylmethoxy]phenyl]propyl]-2H-1,2,3-triazole

Reaction Steps

In substantially the same manner as in Working Example 8, 1,2,3-triazole was allowed to react with 3-[4-[2-[(E)-2-phenylethenyl]-4-oxazolylmethoxy]phenyl]propyl methanesulfonate. The reaction mixture 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-1,2,3-triazole was obtained. The yield was 35%. Recrystallization from ethyl acetate-hexane gave colorless prisms, mp 103-104° C.
