실험 절차

3.07 g (30.6 mmol) of succinic anhydride was suspended in 30 ml of dichloromethane. 4.1 ml (34.5 mmol) of t-butylamine was dropped into the suspension, and the resultant mixture was stirred at room temperature for 1 hour. White crystals thus formed were washed with ethyl acetate and then dissolved in 40 ml of 1 N aqueous sodium hydroxide solution. The resultant solution was stirred at room temperature for 2 hours and then acidified with 1 N aqueous hydrochloric acid solution under cooling with ice. After extracting with ethyl acetate, the organic layer was dried over anhydrous sodium sulfate and then concentrated under reduced pressure to obtain the title compound.
