Hydrogen chloride-ethyl acetate → 1-(2-(4-((2,3-Dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-7-methoxy-5-propionyl-1,2-dihydro-2-oxoquinoline hydrochloride

Participants

Reaction Steps

To 1 mL of an ethyl acetate solution containing 30 mg of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(7-methoxy-2-oxo-5-propionylquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate, 1 mL of 4 mol/L hydrogen chloride/ethyl acetate was added, and stirred at room temperature. The resulting solid was filtered to give 18 mg of 1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-7-methoxy-5-propionyl-1,2-dihydro-2-oxoquinoline hydrochloride as a white solid.
