22.4 g (0.10 mol) of triethylphosphonoacetate was dissolved in 500 ml of tetrahydrofuran and 12.4 g (1.1 mol) of potassium t-butoxide was slowly added thereto. To this solution was slowly added 15.6 g (0.10 mol) of 1-naphtaldehyde dissolved in 20 ml of tetrahydrofuran and the mixture was stirred for 8 hours. The organic solvent was removed by distillation under reduced pressure. The residue was dissolved in ethyl acetate, washed twice with water, dried over anhydrous magnesium sulfate, concentrated and subjected to column chromatography(eluent: hexane/ethyl acetate=95/5, v/v) to give 20.3 g (0.090 mol, Yield 90%) of the title compound.
