실험 절차

2 g of benzoin with 15 ml of acetic anhydride and a few drops of sulphuric acid are added to a reactor with stirring and at room temperature (25° C.) for 15 hours. Water and dichloromethane are added to the reaction mixture. The organic phase is recovered after separating by settling, dried over sodium sulphate, filtered and then concentrated to dryness under vacuum.
