Procedure

Triethylamine (0.46 g) was added to a stirred suspension of 3-[4-(2-aminoethyl)imidazol-1-yl]-N-[1-(4-chlorophenyl)-1-methylethyl]propylamine trihydrochloride (0.65 g) in dichloromethane (20 ml). The solution was cooled to 0° C. and benzenesulphonyl chloride (0.27 g) in dichloromethane (10 ml) was added dropwise with stirring. The mixture was stirred at 0° C. for 30 minutes and then at ambient temperature for 3 hours. The mixture was washed with water, sodium bicarbonate solution and then dried, filtered and evaporated to give a yellow oil which was dissolved in alcohol and treated with ethereal hydrogen chloride. The resulting salt was hygroscopic and so was converted back to the free base by treatment with aqueous sodium hydroxide solution to give N-[2-(1-{3-[1-(4-chlorophenyl)-1-methylethylamino]propyl)imidazol-4-yl)ethyl]benzenesulphonamide as an oil.
