Procedure

To 2 mL of an ethanol solution containing 0.10 g of ethyl (2E)-3-(1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-7-methoxy-2-oxo-1,2-dihydroquinolin-5-yl)acrylate, 0.22 mL of 20% aqueous sodium hydroxide solution was added and stirred at room temperature for 3 hours. Ethanol was removed under reduced pressure, water was added, and adjusted to pH 6.0 with 1 mol/L hydrochloric acid under ice-cooling. The resulting solid was filtered to afford 85 mg of (2E)-3-(1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-7-methoxy-2-oxo-1,2-dihydroquinolin-5-yl)acrylic acid as a light brown solid.
