Procedure

Reaction was carried out in the same manner as in Example 19-(b) except for using tert-butyl[tert-butoxycarbonyl(6-{[4-(5-methylthiazol-2-yl)benzyl](pyridin-2-ylsulfonyl)aminomethyl}pyridin-2-yl)amino]acetate (269 mg, 0.404 mmol) obtained in Example 22-(c) in place of tert-butyl[tert-butoxycarbonyl(6-{[4-(pyridin-2-yl)benzyl]-(pyridin-3-ylsulfonyl)aminomethyl}pyridin-2-yl)amino]acetate. After completion of the reaction, water (20 ml) was added to the reaction solution, then it was adjusted to pH 10.9 with a 1N aqueous sodium hydroxide solution, and subsequently insolubles were filtered off. The filtrate was adjusted to pH 5.6 with 1N hydrochloric acid, followed by extraction with ethyl acetate. The separated organic layer was dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure. To the resulting residue were added tert-butyl methylether (1 ml) and diisopropyl ether (10 ml), followed by sonication. A precipitated solid was collected by filtration, and then dried under reduced pressure to afford the title compound (113 mg) as a white solid. (Yield: 55%)
