Procedure

2-Chloro-5-nitro-benzoyl chloride in 60 mL of diethyl ether was added to an ice-cooled mixture of o-aminophenol (5.4 g) and sodium bicarbonate (8.3 g), water (36 mL) and ether (20 mL) over a period of 1 hour. The mixture was allowed to warm to room temperature and stirred overnight. The precipitate was filtered and washed sequentially with water (3×100 mL), 2N HCl (3×100 mL) and diethyl ether (3×50 mL). Yield 11.2 g (77%).
