New learning discoveries about 641-70-3

The synthetic route of 641-70-3 has been constantly updated, and we look forward to future research findings.

641-70-3, 3-Nitrophthalic anhydride is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

Et3N (23.27 g, 0.23 mol) was added dropwise into the solution of 3-nitro-phthalic anhydride (7, 44.0 g, 0.23 mol) and 3-aminopiperidine-2,6-dione hydrochloride (8, 37.9 g, 0.23 mol) in THF (600 ml). After reacting for 30 min below 20 C, the precipitation was filtered, washed with THF (30 mL¡Á3), and then dried in vacuo to give intermediate 11 (67.20 g, 91.0%) as a white solid (HPLC, 95.24%).

The synthetic route of 641-70-3 has been constantly updated, and we look forward to future research findings.
