실험 절차

A suspension of 0.2 g of platinum oxide in 25 ml of ethanol is treated with hydrogen and a solution of 34.8 g (0.3 mol) of levulinic acid and 85 g (0.62 mol) of 3-amino-4,6-dimethylaniline in 300 ml of ethanol is then added. The hydrogenation is carried out at room temperature. The desired pyrrolidinone derivative is obtained in a yield of about 80%.
