Reaction Steps

To 1 mL of a chloroform solution containing 42 mg of tert-butyl(2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(2-oxo-4-(pyridin-4-yl)quinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate, 1 mL of trifluoroacetic acid was added at room temperature and stirred for 3.5 hours, thereafter the solvent was removed under reduced pressure. To the residue thus obtained, chloroform and aqueous saturated sodium hydrogen carbonate solution were added, the organic layer was separated and the aqueous layer was extracted with chloroform. The organic layer and extracts were combined, washed with aqueous saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. To the residue thus obtained, 1 mL of 4 mol/L hydrogen chloride/ethyl acetate was added, the resulting solid was filtered to give 21 mg of (1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-4-(pyridin-4-yl)quinolin-2(1H)-one hydrochloride as a pale yellow solid.
