Reference of 89-40-7, 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. 89-40-7, name is 5-Nitroisoindoline-1,3-dione belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.
General procedure: N-Methylation of phthalimide derivative M11 was obtained by nucleophilic displacement of iodide from alkyl iodide by deprotonated phthalimide. A mixture of appropriate phthalimide, iodoalkane, and potassium carbonate in DMF was stirred for 6-10 h at 70-110 C. After completion, the mixture was poured into an ice/water mixture. The aqueous phase was extracted with dichloromethane. The combined organic phase was washed with 0.1 HCl, brine and was dried over anhydrous sodium sulfate. The desired N-alkylated product was isolated using flash column chromatography.
The synthetic route of 5-Nitroisoindoline-1,3-dione has been constantly updated, and we look forward to future research findings.
