実験手順
Methyl 5-(4-{[(2S,4R)-4-[[(acetyloxy)acetyl](4-chlorophenyl)amino]-2-methyl-3,4-dihydroquinolin-1(2H)-yl]carbonyl}phenyl)-2,2-dimethylpentanoate (100 mg, 0.16 mmol, 1 eq.) was dissolved in methanol/tetrahydrofuran (2/1) (2 ml). A solution of sodium hydroxide (32 mg, 0.81 mmol, 5 eq.) in water (1 ml) was added and reaction mixture heated to 45° C. for 8 h and at room temperature for 20 h. The mixture was concentrated and the residue was acidified with a 1N HCl aqueous solution and extracted with ethyl acetate. The organic layer was washed with brine, dried over magnesium sulfate, filtered and concentrated to give the crude acid. Purification by silica gel chromatography gave pure 5-(4-{[(2S,4R)-4-[(4-chlorophenyl)(glycoloyl)amino]-2-methyl-3,4-dihydroquinolin-1(2H)-yl]carbonyl}phenyl)-2,2-dimethylpentanoic acid (63 mg, 70%).
