반응 단계
A mixture of 0.90 g of the above catechol derivative, 0.836 g of diethyl dibromomalonate and 1.8 g of powdered anhydrous potassium carbonate in 15 ml of acetone is stirred at room temperature for 18 hours. The reaction mixture is filtered and concentrated in vacuo to give 0.708 g of a mixture of diastereomers as a colorless oil.
