Reaction Steps

4-[5-{[(2S,4R)-4-[acetyl(4-chlorophenyl)amino]-2-methyl-3,4-dihydroquinolin-1(2H)-yl]carbonyl}-2-oxopyridin-1(2H)-yl]-2,2-dimethylbutanoic acid was prepared from methyl 4-[5-{[(2S,4R)-4-[acetyl(4-chlorophenyl)amino]-2-methyl-3,4-dihydroquinolin-1(2H)-yl]carbonyl}-2-oxopyridin-1(2H)-yl]-2,2-dimethylbutanoate. methyl 4-[5-{[(2S,4R)-4-[acetyl(4-chlorophenyl)amino]-2-methyl-3,4-dihydroquinolin-1(2H)-yl]carbonyl}-2-oxopyridin-1(2H)-yl]-2,2-dimethylbutanoate (0.010 g, 0.017 mmol) was hydrolyzed to the acid by dissolving in tetrahydrofuran and methanol and sodium hydroxide (1N) was added. The mixture was stirred at room temperature overnight. The mixture was cooled to rt, acidified to pH=5 with 1N HCl to form a white precipitate (0.006 g, 63%). The solid was filtered to give 4-[5-{[(2S,4R)-4-[acetyl(4-chlorophenyl)amino]-2-methyl-3,4-dihydroquinolin-1(2H)-yl]carbonyl}-2-oxopyridin-1(2H)-yl]-2,2-dimethylbutanoic acid.
