Hydrochloric Acid → {N-[3-(1-methyl-2-oxo-1,2-dihydroquinolin-6-yloxy)propyl]-N-(pyridin-4-ylmethyl)amino}acetic acid

Participants

Reaction Steps

A 1N-sodium hydroxide aqueous solution (3 ml) was added to a methanol solution (15 ml) of {N-[3-(1-methyl-2-oxo-1,2-dihydroquinolin-6-yloxy)propyl]-N-(pyridin-4-ylmethyl)amino}acetic acid ethyl ester (614 mg). The mixture was stirred at room temperature overnight. 1N-Hydrochloric acid (3 ml) was added to the reaction mixture and condensed under reduced pressure. Metanol was added to the residue, and the generated insoluble matter was separated by filtration. The filtrate was condensed under reduced pressure to give the title compound (468 mg) as a white amorphous solid.
