tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(6-nitro-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate → tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(6-amino-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate

Participants

Reaction Steps

To 4 mL of a methanol solution containing 200 mg of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(6-nitro-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate, 20 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 180 mg of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(6-amino-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate as a yellow foam.
