Procedure

A mixture of N-[3-(1-trityl-1H-imidazol-4-ylmethoxy)-phenyl]methanesulfonamide (0.63 g, from above) and 1N HCl (10 mL) in acetonitrile (10 mL) was stirred at room temperature overnight. The solvent was removed and the residue was brought to basic pH with saturated potassium carbonate solution. The mixture was extracted with dichloromethane, washed with brine and dried over sodium sulfate. After evaporation of the solvent, the residue was chromatographed on silica gel eluting with methanol (containing 2% NH4OH)/dichloromethane (7:93) to give N-[3-(1H-imidazol-4-ylmethoxy)-phenyl]methanesulfonamide. This was converted to N-[3-(1H-imidazol-4-ylmethoxy)-phenyl]methanesulfonamide oxalate salt, mp 178-180° C. by treating with 1M oxalic acid in ether.
