Introduction of a new synthetic route about 20870-79-5

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. 20870-79-5, name is 5-Nitroindolin-2-one belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below. Safety of 5-Nitroindolin-2-one

Safety of 5-Nitroindolin-2-one

Di-tert-butyl dicarbonate (5.51 g, 25.27 mmol) and sodium hydrogen carbonate (12.73 g, 151.65 mmol) were added to a stined solution of 5-nitroindolin-2-one (3.0 g, 16.85 mmol) in tetrahydrofuran (150 mL) and the mixture was heated to 60 C. After 3h the reaction mixture was cooled and filtered, the filtrate was concentrated in reduced pressure to obtain a crudecompound. The obtained crude was purified by silica gel chromatography using a mixture of10% ethyl acetate/hexane as an eluent to get the desired compound as a white solid (3.68 g,5 1%). ?H-NMR (300 MHz, DMSO- d6) oe 8.3 (m, 1H), 8.2 (s, 1H), 7.9 (m, 1H), 3.8 (s, 2H), 1.5(s, 9H); LC-MS: m/ LC-MS: 278.8 (M+H).

The synthetic route of 20870-79-5 has been constantly updated, and we look forward to future research findings.
