Procedure

According to the same manner as that described in Reference Example 1, 4-isopropoxybenzaldehyde was reacted with triethyl 4-phosphonocrotonate to give ethyl (E,E)-5-(4-isopropoxyphenyl)pentadienoate as crystals (yield: 58%). The crystals were recrystallized from ether-hexane. Colorless prisms, mp: 64-65° C.
