Procedure

To a mixed solution of 5 mL methanol and 0.5 mL water containing 126 mg of ethyl (1-(2-(4-((tert-butoxycarbonyl)(2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-2-oxo-1,2-dihydroquinolin-5-yloxy)acetate, 0.2 mL of 5 mol/L aqueous sodium hydroxide solution was added and allowed to stand at room temperature for 2.5 hours. To the reaction mixture, water was added, and the solvent was removed under reduced pressure. After the residue thus obtained was acidified by adding 1 mol/L hydrochloric acid, it was extracted with chloroform. The extracts were washed with aqueous saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure to give 90 mg of (1-(2-(4-((tert-butoxycarbonyl)(2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-2-oxo-1,2-dihydroquinolin-5-yloxy)acetic acid as a white foam.
