2-Bromo-3-fluorophenol

443-81-2

1. 120 mL of isopropanol, 200 mL of 6M hydrochloric acid and 81 g (345 mmol) of 1-(methoxymethoxy)-2-bromo-3-fluorophenol were mixed and stirred for 2.5 hours at room temperature. 2. Upon completion of the reaction, the reaction mixture was partitioned. 400 ml of methyl tert-butyl ether and 120 ml of 5N sodium hydroxide were added. 3. The organic phase was separated, washed with saturated aqueous sodium chloride solution and then dried over anhydrous sodium sulfate. 4. The dried organic phase is concentrated under pressure to give an oily residue. 5. purify the residue by silica gel column chromatography and collect the fraction containing 2-bromo-3-fluorophenol. 6. Concentrate the combined fractions under pressure to give 55.1 g (84% yield) of the target compound 2-bromo-3-fluorophenol as a colorless oil.
