Reaction Steps

To 2 mL of a chloroform solution containing 0.31 g of methyl 1-(2-(4-((tert-butoxycarbonyl)(2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-7-methoxy-2-oxo-1,2-dihydroquinoline-3-carboxylate, 1 mL of trifluoroacetic acid was added and stirred for 3 hours. The solvent was removed under reduced pressure, and aqueous saturated sodium hydrogen carbonate solution and ethyl acetate were added. The organic layer was separated, and the aqueous layer was extracted twice with ethyl acetate. 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 give 0.22 g of methyl 1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-7-methoxy-2-oxo-1,2-dihydroquinoline-3-carboxylate as a colorless oil.
