Procedure

Dissolve dimethoxyacetaldehyde (97 g, 0.635 mol, 60% in water) and triethylphosphonoacetate (142 g, 0.633 mmol) in 7:1 tetrahydrofuran:water. Add potassium carbonate (100 g, 0.723 mole) and stir for 4 hours at room temperature. Pour the reaction into ethyl acetate (500 ml) and wash with saturated aqueous sodium bicarbonate and saturated aqueous sodium chloride. Concentrate under reduced pressure to provide the desired compound as a clear oil.
