Procedure

To 11 mL of acetone solution containing 1.1 g of methyl 1-(2-(4-((tert-butoxycarbonyl)(2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-2-oxo-1,2-dihydroquinoline-4-carboxylate, 2.2 mL of water solution containing 0.23 g of sodium hydroxide was added at room temperature, and stirred at 50° C. for 30 min. After cooled to the room temperature, the solvent was removed under reduced pressure, 40 mL of water was added, and adjusted to pH 4 with 2 mol/L hydrochloric acid. The resulting solid was filtered to afford 0.97 g of 1-(2-(4-((tert-butoxycarbonyl)(2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-2-oxo-1,2-dihydroquinoline-4-carboxylic acid as a white solid.
