Aqueous 1N HCl (2 mL) was added to a solution of methyl 2-(2-oxo-3,4-dihydro-1,6-naphthyridin-1(2H)-yl)acetate (1.24 g, 5.67 mmol) in acetic acid (5 mL) and the resulting mixture was heated to 60° C. for 4 h. The solution was concentrated under vacuum to give 2-(2-Oxo-3,4-dihydro-1,6-naphthyridin-1(2H)-yl)acetic acid. Retention time (min)=0.275, method [1], MS(ESI) 207.0 (M+H).
