4-Nitro-lH-isoindole-l, 3(2H)-dione (117.3 g; Formula IV) followed by 1,1- carbonyldiimidazole (138.1 g) were added to a slurry of 3-aminopiperidine-2,6-dione hydrochloride (100 g, Formula III; obtained in Example 1) in acetonitrile (800 mL) to obtain a reaction mixture. The reaction mixture was heated to reflux at 80C to 82C and then stirred for 2 hours. 1,1-Carbonyldiimidazole (19.8 g) was further added to the reaction mixture twice over an interval of one hour. The reaction mixture was cooled to 25 C to 30C and then stirred for 30 minutes. The product obtained was filtered and the wet solid obtained was dried at 50C to 55C under reduced pressure to obtain the title compound. (0076) Yield: 162 g (88%)
