59-49-4, 2-Benzoxazolinone is a benzoxazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
3H-1,3-Benzoxazol-2-one (5.00?g, 37.00?mmol) was dissolved in acetic acid (50?mL) and bromine (1.9?mL, 37.0?mmol) was added dropwise. The reaction mixture was stirred at 20?C for 4?h.The reaction mixture was poured onto ice and the precipitate was collected by filtration, washed with water and air-dried to give a pink powder (7.48?g, 34.8?mmol, 94%). Mp 191.6-192.3?C. 1H NMR (300?MHz, DMSOd6): delta 11.81 (s, 1H), 7.57 (dd, J?=?1.9?Hz, J?=?0.3?Hz, 1H), 7.30 (dd, J?=?8.3?Hz, J?=?1.9?Hz, 1H), 7.04 (dd, J?=?8.3?Hz, J?=?0.3?Hz, 1H). 13C NMR (75?MHz, DMSOd6): delta 154.5, 144.5, 130.3, 126.9, 113.5, 113.2, 111.7. LCMS m/z calc for [M?-?H]+: 211.9, 213.9, found: 211.8, 213.8., 59-49-4
As the paragraph descriping shows that 59-49-4 is playing an increasingly important role.
