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

Participants

Reaction Steps

Reaction and post-treatment were carried out in the same manlier as in Example 21-(b) except for using tert-butyl[tert-butoxycarbonyl(6-{(pyridin-2-ylsulfonyl)[4-(4-trifluoromethylthiazol-2-yl)benzyl]aminomethyl}pyridin-2-yl)amino]acetate (440 mg, 0.611 mmol) obtained in Example 25-(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 (293 mg) as a white solid. (Yield: 85%)
