実験手順

To a solution of N-[3-(3-amidinophenyl)-2-(E)-propenyl]-N-[3-carbamoyl-4-[1-(4,5-dihydro-3H-pyrrol-2-yl)piperidin-4-yloxy]phenyl]methanesulfonamide dihydrochloride (0.30 g) obtained in example 99(b) in a mixture of dichloromethane (4 ml) and acetonitrile (4 ml) were added successively 4-nitrophenyl benzoate (0.15 g) and triethylamine (0.28 ml) with stirring under ice-cooling, and the resulting mixture was stirred at room temperature overnight. After stirring, the reaction mixture was diluted with dichloromethane, and the organic layer was washed successively with a 0.5N aqueous sodium hydroxide solution and a saturated aqueous sodium chloride solution, dried over anhydrous sodium sulfate and evaporated in vacuo. The residue obtained was purified by chromatography on a silica gel column using a mixed solvent of dichloromethane and methanol (50:0˜47:3). The purified solid obtained was dissolved in water and then lyophilized to afford the title compound (0.24 g, yield: 75%) as a pale yellow amorphous solid.
