59-49-4, 2-Benzoxazolinone is a benzoxazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
40.0 g (0.30 mol) of 2-benzoxazolinone were dissolved with stirring at room temperature in 600.0 ml (0.30 mole) of 68% nitric acid. It was then heated to 50 C. and stirred at this temperature for three hours. The reaction was stirred for a further 16 h at room temperature. After completion of the reaction, the mixture was poured into about 2.0 l of ice water, precipitated substance was filtered off, washed neutral and dried. After drying, 6-nitro-3H-1,3-benzoxazol-2-one (39.1 g, 72%) was obtained as a pale yellow solid. 1H-NMR (300 MHz, d6-DMSO): delta=7.25 (d, 1H, 4-H), 8.10 (d, 1H, 5-H), 8.17 (s, 1H, 7-H), 12.43 (br s, 1H, NH)., 59-49-4
The synthetic route of 59-49-4 has been constantly updated, and we look forward to future research findings.
