Trifluoroacetic acid → HCID 59398333, compound

Participants

Reaction Steps

To 2 mL of a chloroform solution containing 97 mg of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(3-methyl-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate, 2 mL of trifluoroacetic acid was added and stirred at room temperature for 4 hours. After the solvent was removed under reduced pressure and the residue was alkalized by aqueous saturated sodium hydrogen carbonate solution, it was extracted with ethyl acetate. The organic layer was washed sequentially with water and aqueous saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure to give 78 mg of 1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-3-methylquinolin-2(1H)-one as a pale yellow solid.
