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 31 mg of ethyl isocyanate were added, and stirred at room temperature for 3 days. The reaction mixture was purified by silica gel column chromatography [Silica Gel; Fuji Silysia Chemical Ltd., Chromatorex-NH, eluent; ethyl acetate: methanol=10:1], to give 60 mg of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(5-(3-ethylureido)-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate as a yellow oil.
