Procedure

To 2 mL of a chloroform solution containing 80 mg of tert-butyl(2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(5-amino-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate, 45 mg of triethylamine and 42 mg of methyl chloroformate were added, and stirred at room temperature for 3 days. To the reaction mixture, 225 mg of triethylamine and 210 mg of methyl chloroformate were added, and stirred at room temperature overnight. The reaction mixture was purified by silica gel column chromatography [Silica Gel; Fuji Silysia Chemical Ltd., Chromatorex-NH, eluent; hexane:ethyl acetate=1:4], to give 40 mg of N-(1-(2-(4-((tert-butoxycarbonyl)(2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-2-oxo-1,2-dihydroquinolin-5-yl)carbamic acid methyl ester as a pale yellow oil.
