1,4-Dioxane hydrochloride → 1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-5-(1-hydroxypropyl)-7-methoxyquinolin-2(1H)-one hydrochloride

Participants

Reaction Steps

To 1 mL of a 1,4-dioxane solution containing 165 mg of tert-butyl(2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(5-(1-hydroxypropyl)-7-methoxy-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate, 1 mL of 4 mol/L hydrogen chloride/1,4-dioxane were added, and stirred at room temperature. The solvent was removed under reduced pressure to give 24 mg of 1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-5-(1-hydroxypropyl)-7-methoxyquinolin-2(1H)-one hydrochloride as a brown solid.
