반응 단계

N-(5-Aminomethyl-5,6,7,8-tetrahydro-naphthalen-2-yl)-benzenesulfonamide and 2-methylsulfanyl-4,5-dihydro-1H-imidazole hydroiodide were added to methylene chloride and the reaction mixture was heated to reflux until all of the solvent evaporates. The reaction mixture is heated to 150° C. and then cooled. The resulting mixture is basified by dropwise addition of aqueous NaOH solution, and then purified by preparative liquid chromatography to give N-{5-[(4,5-Dihydro-1H-imidazol-2-ylamino)-methyl]-5,6,7,8-tetrahydro-naphthalen-2-yl}-benzenesulfonamide. 5-[(4,5-Dihydro-1H-imidazol-2-ylamino)-methyl]-5,6,7,8-tetrahydro-napthalene-2-sulfonic acid phenylamide may be similarly prepared.
