12.65 mmol of succinic anhydride (1.266 g), 12.65 mmol of 4-dimethylaminopyridine (1.546 g) and 10.75 mmol of ditetradecylamine (4.407 g) were successively added to 125 ml of dichloromethane in a round-bottomed flask. The reaction mixture was stirred for 18 hours at room temperature. Once the reaction was complete, the mixture was extracted with dichloromethane and hydrochloric acid (1N). The organic phase was then washed with brine and dried over magnesium sulfate, filtered and then concentrated to give 4.21 g of product (3) (yield: 66%).
