99% | With sodium hydroxide In dichloromethane; water at 20℃; for 22 h; | 2-Bromo-4-chloro-1-methoxybenzene (47). A solution of sodium hydroxide (836 mg, 20.9 mmol) in water (8.0 mL) was added to a solution of 2-bromo-4-chlorophenol (45) (2.1 g, 9.92 mmol) and tetrabutylammonium bromide (336.4 mg, 1.03 mmol) in dichloromethane. Dimethyl sulfate (1.5 mL, 15.69 mmol) was added. The resulting mixture was stirred at room temperature for 22 h and then 1 N aq HCl (about 2 mL) was added to quench the reaction. The organic phase was separated and the aqueous phase was extracted with dichloromethane (2.x.15 mL). The combined organic phase was washed with brine, dried over sodium sulfate and concentrated to afford an oil. The crude product was purified by column chromatography on silica gel (10 g) using EtOAc-hexanes (5percent) to afford the product 47 as a colorless oil (2.17 g) in 99percent yield. See, Dischino, D.
