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

Participants

Reaction Steps

To a mixed solution of 130 mL methanol and 10 mL tetrahydrofuran containing 1.76 g of tert-butyl (1-(2-(4-benzyloxy-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)(2,3-dihydro-1,4-benzodioxin-6-ylmethyl)carbamate, 0.86 g of 5% palladium on carbon was added, and stirred under hydrogen atmosphere for 3.5 hours. The insoluble material was filtered off, and the solvent was removed under reduced pressure to afford 1.48 g of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(4-hydroxy-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate as a white solid.
