Reaction Steps

The amine of step 5 (4.8 g, 0.01 mole), succinic anhydride (1.2 g, 0.012 mole), and triethylamine (2.2 g, 0.02 mole) in chloroform (150 mL) were heated for 30 min at 50°-60° C. (hot water) and allowed to stir at ambient temperature for 16 hrs. Dichloromethane (200 mL) was added, the mixture was washed with 10% hydrochloric acid solution (3×100 mL). saturated sodium chloride solution (100 mL), dried over anhydrous magnesium sulfate, filtered, and the solvent removed on a rotary evaporator in vacuo to give a white solid, 3.3 g (66%). This material was chromatographed using a SiO2 column to give a white solid.
