Participants

Reaction Steps

3-[4-(2-Aminoethyl)imidazol-1-yl]-N-(1,1-dimethyl-2-phenoxyethyl)propylamine (2.05 g) was reacted with benzenesulphonyl chloride (1.15 g) in a similar manner to Example 55 to give N-(2-{1-3-(1,1-dimethyl-2-phenoxyethylamino)propyl]imidazol-4-yl}ethyl]benzenesulphonamide, as an oil. The compound contained 7% of N-(2-{1-[3-(1,1-dimethyl-2-phenoxyethylamino)propyl]imidazol-5-yl}ethyl]benzenesulphonamide, by 1H nmr and 13C nmr. These compounds may be separated by HPLC.
