Reaction Steps

5,6,7,8-Tetrahydronaphthalen-1-ylamine (1.4 ml, 15 mmol) is brought to the reflux point of 1-butanol (50 ml) in the presence of bis(2-chloroethyl)amine hydrochloride (2.68 g, 15 mmol) and sodium carbonate (800 mg, 7.5 mmol). After 48 h, the reaction mixture is concentrated and impregnated onto silica and then purified by flash chromatography with a mixture (95/5/1) and then (90/9/1) of dichloromethane/methanol/aqueous ammonia.
