59-49-4, 2-Benzoxazolinone is a benzoxazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

6-chloro-3-methylbenzo[d]oxazol-2(3H)-one (S8). 60% sodium hydride (1.44 g, 36 mmol) wasadded to a solution of benzoxindolidinone (3.38 g, 25 mmol) in THF (20 mL) at 0 C, and stirredat 0 C for 30 minutes. Iodomethane (2.30 mL, 37.5 mmol) was added dropwise and stirred at room temperature for 9 hours. The reaction mixture was diluted with ethanol and concentrated.The residue was diluted with water and extracted with dichloromethane. The organic layers werecombined, dried over sodium sulfate, filtered, and concentrated. The product was purified bycolumn chromatography eluting with 25% ethyl acetate/hexanes to yield S8 (1.62 g, 43%) as anoff white solid.Rf: 0.25 (25% ethyl acetate/hexanes)1H NMR (400 MHz, CDCl3): delta = 7.22 – 7.17 (m, 2H), 7.15 – 7.09 (m, 1H), 6.98 – 6.95 (m, 1H),3.41 (s, 3H)13C NMR (101 MHz, CDCl3): delta = 154.9, 142.8, 131.9, 124.0, 122.6, 110.1, 108.2, 28.2
