Procedure
3-Aminophenol (2 g, 18 mmol) is brought to the reflux point of 1-butanol (30 ml) in the presence of 2-chloro-N-(chloroethyl)-N-methylethanamine hydrochloride (3.5 g, 18 mmol) and sodium carbonate (95 mg, 9 mmol). After 48 h, the reaction mixture is concentrated and adsorbed on silica and then purified by flash chromatography with a mixture (90/10) of dichloromethane/methanol.
