Procedure

To 11 mL of a methanol solution containing 0.65 g of butyl 1-(2-(4-((tert-butoxycarbonyl) (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-4-methyl-2-oxo-1,2-dihydroquinoline-7-carboxylate, 55 mg of lithium hydroxide monohydrate was added and stirred for 30 min. Then, 55 mg of lithium hydroxide monohydrate and 1.1 mL of water were added and stirred for 2 hours. The methanol was removed under reduced pressure, water and chloroform were added, and adjusted to pH 5.0 with acetic acid. The organic layer was separated, and the aqueous layer was extracted with chloroform. The organic layer and extracts were combined, washed with aqueous saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure to give 0.60 g of 1-(2-(4-((tert-butoxycarbonyl)(2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-4-methyl-2-oxo-1,2-dihydroquinoline-7-carboxylic acid as a white foam.
