Following a procedure similar to that described in the first part of Preparation 3, 7.00 g of 3-(3-methoxymethoxyphenyl)-2-propenal and 18 g of 2-benzyloxybenzyltriphenylphosphonium chloride (prepared as described in Preparation 1) were dissolved in 200 ml of acetonitrile, with heating, and 5.54 g of 1,8-diazabicyclo[5,4,0]undec-7-ene were added to the mixture and reacted. The crude product, extracted as described in Preparation 3, was purified as described in Preparation 3, to give 12.0 g of 1-(2-benzyloxyphenyl)-4-(3-methoxymethoxyphenyl)butadiene as a colorless oil.
