실험 절차

A suspension comprising 25 millimoles of potassium phthalimide and 20 ml of methylchloroformate is refluxed for a period of approximately 31/2 hours. Upon completion of refluxing, the reaction mediuim is cooled, filtered, with insolubles being removed continuously by treatment with hot acteone until only potassium chloride remains. The desired product m.p. 184° - 184.5°C., is obtained from the acetone.
