Reaction Steps

In 200 ml of ethanol, 16.2 g of sodium methoxide were dissolved. Into this solution, 49.5 g of diethyl malonate were dropped and gently refluxed. 37.98 g of benzyl chloride were dropped into the mixture over one hour and the mixture was refluxed for 2 hours. After the reaction was completed, the solvent was removed under reduced pressure, and water was added to the residue. After extraction with ethyl acetate, the ethyl acetate was dried with sodium sulfate anhydride. After removing the solvent under reduced pressure, followed by purification with distillation, 50 g of 2-benzylmalonic acid diethyl ester were obtained.
