実験手順
To a solution of N-[4-(2-{[(tert-butyl)amino]sulfonyl}phenyl)phenyl][2-(3-cyanophenyl)cyclopent-1-enyl]carboxamide (70 mg, 0.137 mmol) in 5 ml anhydrous methanol cooled in an ice bath was bubbled HCl gas until saturation was achieved. Reaction was allowed to warm to room temperature and stirred overnight. The reaction was then concentrated in vacuo and dried under hi vacuum. The dried residue was dissolved in 5 ml anhydrous methanol to which ammonium acetate (77 mg, 1 mmol) was added and the reaction heated to reflux for 2 hours. The reaction was concentrated and purified on a 2×25 cm Vydac C18 HPLC column to give 3-(2-{N-[4-(2-sulfamoylphenyl)phenyl]carbamoyl}cyclopent-1-enyl)benzenecarboxamidine (40 mg, 63%) as a fluffy white powder after lyophilization. ES-MS (M+H+): 461.15
