4-BROMO-2,6-DIFLUOROPHENOL Use and Manufacturing

Methods of Manufacturing

Intermediate 110N-Bromosuccinimide (3.60 g, 20.2 mmol) was added to a stirred solution of 2, 5-difluorophenol (2.61 g, 20.1 mmol) in DMF (10 mL) at 0 °C. The reaction mixture was stirred for 24 h at rt with shielding from light, then the reaction was quenched with H2, 6-Difluorophenol (1.02 g, 7.8 mmol) was dissolved in 15 mL of DMF, and at 0 NBS (1.40 g, 7.84 mmol) was added thereto. The reaction mixture was stirred for 24 hours at room temperature and concentrated. 50 mL of water was added thereto, and the mixture was extracted with Et2, 6-Difluorophenol (1.02 g, 7.8 mmol) was dissolve in 15 mL of DMF. NBS (1.40 g, 7.84 mmol) was added thereto at 0°C, and the mixture was stirred at room temperature for 24 hours. The reaction solution was concentrated, and 50 mL of water was added thereto. The reaction solution was extracted with Et2O and dried with MgSO4 to obtainthe title compound (1.41 g, 86percent).1H NMR (CDCl3) δ 7.08 (2H, m), 5.42 (1H, brs)To a solution of diisopropylamine (7.06 mL, 0.05 mol, leq), in THF (100 mL) under argon, cooled at -40
