Reaction Steps

A solution of benzenesulphonyl chloride (0.51 g) in dichloromethane (5 ml) was added in portions over 5 minutes to a solution of 4-{1-[3-(imidazol-1-yl)propylamino]-1-methylethyl}phenol (0.75 g) and triethylamine (0.29 g) in dichloromethane (5 ml) at 0° C. with stirring. The mixture was stirred at ambient temperature for 3 hours then diluted with dichloromethane and washed with water. The organic layer was separated, dried and evaporated. The residue was purified by flash column chromatography on silica using methanol as the mobile phase to give 4-{1-[3-(imidazol-1-yl)propylamino]-1-methylethyl}phenyl benzenesulphonate as an oil.
