실험 절차

To a solution of 1-(4-Ethoxycarbonyl-phenyl)-2-oxo-1,2-dihydro-pyridine-4-carboxylic acid (1.155 g) in THF (20 mL) at 0° C. was added 5 M sodium hydroxide (1.19 mL) and mixture stirred overnight at ambient temperature. Reaction mixture was acidified to pH 1 with concentrated HCl, producing a precipitate. The solid was collected by filtration, washed with H2O and dried under high vacuum to give 1-(4-Carboxy-phenyl)-2-oxo-1,2-dihydro-pyridine-4-carboxylic acid (0.7196 g). LCMS-ESI−: calc'd for C13H8NO5: 258.2 (M−H+). Found: 258.1 (M−H+).
