실험 절차
20.87 g (0.141 mol) of phthalic anhydride together with 16.5 g (0.141 mol) of ethyl aminopropionate in an open round-bottom flask at 120° C. for 5 h. 300 ml of cyclohexane are added, and the mixture is heated to reflux. The hot cyclohexane solution is decanted off from the remaining oil and completely concentrated. A slowly solidifying viscous oil is obtained (31 g, 89% yield).
