88% | With potassium permanganate; sodium hydroxide In water at 20℃; for 2 h; Cooling with ice | 2-Bromo-4-hydroxybenzaldehyde (1.7 g, 8.46 mmol, 1.0 eq.)Dissolved in 2 moles of aqueous sodium hydroxide solution (30 ml),Under ice bath conditions,Potassium permanganate (2.7 g, 616.92 mmol, 2.0 equiv) was added in portions,Warm to room temperature and stir for 2 hours.After filtration, the filtrate was washed once with dichloromethane, and 2 mol per liter of aqueous hydrochloric acid was added to the filtrate to adjust the pH to 1. The mixture was extracted with ethyl acetate, and the organic phase was dried over anhydrous sodium sulfate and evaporated.The product as a white solid was obtained 2-bromo-4-hydroxybenzoic acid (1.6 g, 88percent). |
