To 3 mL of a methanol solution containing 150 mg of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(5-nitro-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate, 15 mg of 10% palladium on carbon was added under nitrogen atmosphere, then stirred under hydrogen atmosphere at room temperature for 2 hours. The insoluble material was filtered off, and the solvent was removed under reduced pressure to afford 140 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 as a yellow oil.
