Reaction Conditions

Temperature47.5 °C

Reaction Steps

To 15 mL of a methanol solution containing 0.11 g of 1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-7-methoxyquinolin-2(1H)-one hydrochloride, 50 mg of 10% palladium on carbon was added, and stirred under hydrogen atmosphere at 45-50° C. for 8.5 hours. The insoluble material was filtered off, the solvent was removed under reduced pressure to afford 0.15 g of 1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-7-methoxy-3,4-dihydroquinolin-2(1H)-one hydrochloride as a yellow foam.
