Procedure
Reaction was carried out in the same manlier as in Example 19-(b) except for using tert-butyl[tert-butoxycarbonyl(6-{(pyridin-3-ylsulfonyl)[4-(1,2,4-triazol-1-yl)benzyl]aminomethyl}pyridin-2-yl)amino]acetate (936 mg, 1.47 mmol) obtained in Example 20-(a) 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, the reaction solution was concentrated under reduced pressure. The concentrate was adjusted to pH 4.5 with a 6N aqueous sodium hydroxide solution, and a precipitated solid was collected by filtration. Acetone (1.3 ml) was added to the crude product, followed by stirring at 50° C. for 1 hour, and then at room temperature for 1 hour. A precipitated solid was collected by filtration, and then dried under reduced pressure to afford the title compound (618 mg) as a white solid. (Yield: 88%)
