Reaction Steps

A solution of ethyl 3-oxo-3-phenylpropanoate (23.74 g) in toluene, ethyleneglycol (23.04 g), and p-toluenesulfonic acid (200 mg) in toluene (300 mL) was stirred under reflux with a Dean-Stark trap for 15 hours. The cooled mixture was poured onto saturated aqueous sodium bicarbonate (100 mL) and the organic layer was washed with water, brine and dried over Na2SO4. Filtration and evaporation of solvent provided the title compound which was used in the next reaction without further purification.
