In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 3416-57-7, name is 2-(2-Oxopropyl)isoindoline-1,3-dione belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below. 3416-57-7
To a refluxed mixture of 4.63 M sodium methoxide in methanol (55.0 mL, 254 mmol) and methanol (500 mL) was added solid N-acethonylphthalimide (25.00 g, 123.0 mmol, from TCI) in one portion. After addition, the reaction was heated at reflux for 2 hours, then cooled at 0 C and neutralized with 1 N HCl. The resulting suspension was stirred at 0 C for 30 minutes and then filtered under reduced pressure, washed with a small amount of water and air dried. The resulting solid was further dried under vacuum, over P2O5, to give the desired product (21.2 g, 85%). LCMS calculated for CnHi0NO3 (M+H)+: m/z = 204.1; Found: 204.0.
The synthetic route of 3416-57-7 has been constantly updated, and we look forward to future research findings.
