86% | With potassium hydrogen difluoride; dihydrogen peroxide; In water; N,N-dimethyl-formamide; at 20℃; for 16h; | General procedure: [00184] To C (79,3 mg, 0.189 mmol) in DMF (0.6 ml.) was added KHF2 (44.3 mg, 0.567 mmol, 3.0 equiv) and H202 (56 of 30percent w/w in H20, 0,49 mmol, 2.6 equiv), and the mixture was stirred at room temperature for 16 h and then partitioned between H20 and ethyl acetate (4 mL each). The organic layer was separated, and the aqueous layer was extracted with ethyl acetate (4 mL). The combined organic layer was washed with H20 (3 mL) and brine (2 mL), dried over MgS04, and concentrated. The residue was purified by flash column chromatography (0 -> 50percent ethyl acetate in hexanes) to afford the product as a colorless solid (35.3 mg, 87percent yield). : 1 NMR (500 MHz, CDCk) delta 7.62 (s, 1H), 7.46 - 7.42 (m, 1H), 7.25 (d, J= 0.9 Hz, IH), 6.55 (bs, IH), 2.59 (s, 3H). 13C MR (126 MHz, CDCI3) delta 197.94 (s), 157.18 (s), 139.47 (s), 124.30 (s), 123.89 (s), 123.30 (s), 113.94 (s), 26.96 (s). HRMS (ESI-) calcd for [C8H6Br02-] ( -H+): 212.9557, found: 212.9557. |
