Reaction Steps

To the solution of methyl 4-(4-{[(2S,4R)-4-[acetyl(4-chlorophenyl)amino]-2-methyl-3,4-dihydroquinolin-1(2H)-yl]carbonyl}-2-fluorophenoxy)-2,2-dimethylbutanoate (176 mg, 0.30 mmol) in MeOH/THF (1 mL/1 mL) was added excessive LiOH (1N aqueous solution). The reaction mixture was stirred at r.t. overnight. The reaction was quenched by adding 6N HCl to PH 2. The mixture was concentrated under reduced pressure to remove MeOH and THF. DCM (30 mL) was added. The reaction mixture was washed with brine (30 mL). The organic layer was dried over magnesium sulfate, filtered, and concentrated under reduced pressure. The crude residue was purified by silica gel chromatography (hexanes-ethyl acetate system) to afford slightly yellow solid product (120 mg, 70%).
