Participants

Reaction Steps

An aqueous 1 M sodium hydroxide solution (3.0 ml) was added to an ethanol (5 ml)-tetrahydrofuran (5 ml) solution of ethyl 1-{2-[3-(4-{[(2-{[(5-chloropyridin-2-yl)amino]carbonyl}-6-hydroxyphenyl)amino]carbonyl}phenyl)-2-oxopyridin-1(2H)-yl]ethyl}piperidine-4-carboxylate (392 mg), followed by stirring at room temperature for 19 hours. 1 M hydrochloric acid (3.0 ml) and water (50 ml) were added to the reaction mixture, followed by extraction with chloroform-isopropanol. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure to obtain 1-{2-[3-(4-{[(2-{[(5-chloropyridin-2-yl)amino]carbonyl}-6-hydroxyphenyl)amino]carbonyl}phenyl)-2-oxopyridin-1(2H)-yl]ethyl}piperidine-4-carboxylic acid (332 mg) as a pale yellow solid.
