15.0 g of PPE, 2.65 g (15.2 mmol) of the compound (12) and 4.50 g (13.4 mmol) of 4-octyloxy-4'-hydroxybiphenyl were dissolved in 120 ml of chloroform under an argon gas atmosphere and the whole was stirred at room temperature overnight. After addition of water to the reaction mixture, the whole was extracted with methylene chloride. After removal of the solvent by distillation, the residue was purified by silica gel column chromatography to obtain 5.30 g of 4- (4'-octyloxybiphenyl p-allyloxybenzoate (25) as a white solid (yield: 86.2%).
