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%)

We’ll be discussing some of the latest developments in chemical about CAS: 603-62-3. Recommanded Product: 3-Nitrophthalimide

General procedure: A mixture of the appropriate thiol (6 mmol), 3-nitrophthalimide(4 mmol) and K2CO3 (10 mmol) in 20 mL acetone was heated underreflux for 24 h. The reaction was cooled to room temperature anddiluted with 150 mL water. The mixture was subsequently acidifiedto pH 2 with 6 N HCl. The resulting precipitate was collectedby filtration and dried at 50 C [19].

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. In my other articles, you can also check out more blogs about 603-62-3.
