Procedure

To 3.0 mL of tetrahydrofuran suspension containing 0.15 g of 1-(2-(4-((tert-butoxycarbonyl)(2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-7-methoxy-2-oxo-1,2-dihydroquinoline-4-carboxylic acid, 39 μL, of triethylamine was added at room temperature, 25 μL of ethyl chlorocarbonate was added dropwise under ice-cooling, and the reaction mixture was stirred at the same temperature for 2 hours. Then, 15 μL of 2-aminoethanol was added dropwise. After stirred at the same temperature for 3 hours, 15 μL of 2-aminoethanol was added dropwise and stirred for 1.5 hours. Further, 15 μL of 2-aminoethanol was added dropwise and stirred at room temperature for 40 min. To the reaction mixture, ethyl acetate and water were added, the organic layer was separated, and the aqueous layer was extracted with ethyl acetate. The organic layer and extracts were combined, washed sequentially with water and aqueous saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. To the residue thus obtained, diethyl ether and diisopropyl ether were added, and the resulting solid was filtered to give 84 mg of tert-butyl(2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(4-(((2-hydroxyethyl)amino)carbonyl)-7-methoxy-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate as a slight yellow solid.
