Tert-butyl [tert-butoxycarbonyl(6-{[4-(pyrazol-1-yl)benzyl](pyridin-2-ylsulfonyl)aminomethyl]pyridin-2-yl)amino}acetate → (6-{(4-Fluorobenzenesulfonyl)[4-(pyrazol-1-yl)benzyl]aminomethyl}pyridin-2-ylamino)acetic acid

Participants

Reaction Steps

Reaction and post-treatment were carried out in the same manner as in Example 21-(b) except for using tert-butyl[tert-butoxycarbonyl(6-{(4-fluorobenzenesulfonyl)[4-(pyrazol-1-yl)benzyl]aminomethyl}pyridin-2-yl)amino]acetate (794 mg, 1.22 mmol) obtained in Example 26-(a) in place of tert-butyl[tert-butoxycarbonyl(6-{[4-(pyrazol-1-yl)benzyl](pyridin-2-ylsulfonyl)aminomethyl}pyridin-2-yl)amino]-acetate to afford the title compound (517 mg) as a white solid.
