Participants

Reaction Steps

Acetic anhydride (21.2 ml, 220 mmol) was slowly added to a suspension of m-aminophenol (24.0 g, 220 mmol) in 60% of crushed ice and 60 ml of cold water. The reaction mixture was vigorously stirred for 30 minutes. The white precipitate was filtered, washed with cold water, and air-dried to give 30.5 g (92%) of pure 3-acetamidophenol, m.p. 147-149° C.
