실험 절차

To a solution of tert-butyl[tert-butoxycarbonyl(6-{[4-(pyridin-2-yl)benzyl]-(pyridin-3-ylsulfonyl)aminomethyl}pyridin-2-yl)amino]acetate (1.76 g) (containing 1.95 mmol of a pure content) obtained in Example 19-(a) in tetrahydrofuran (5.6 ml) were added water (5.6 ml) and concentrated hydrochloric acid (2.3 ml), followed by stirring at 65° C. for 4.5 hours. After completion of the reaction, the reaction solution was concentrated under reduced pressure. After the concentrate was adjusted to pH 10.9 with a 1N aqueous sodium hydroxide solution, the insolubles were filtered off. The filtrate was then adjusted to pH 5.6 with 1N hydrochloric acid, followed by addition of ethyl acetate. A precipitated solid was collected by filtration, and then dried under reduced pressure to afford the title compound (553 mg) as a white solid. (Yield: 58%)
