実験手順
A 100 mL round-bottomed flask was charged with methyl 1-(4-fluorophenyl)-6-oxo-1,6-dihydropyridine-3-carboxylate (2.3 g, 9.1 mmol) and 20 mL of EtOH. To this was added NaOH (1.10 g, 27.0 mmol). This solution was stirred at rt for 20 h then concentrated. The mixture was acidified to pH 1 with conc HCl. The resulting precipitate was filtered and dried to give 1-(4-fluorophenyl)-6-oxo-1,6-dihydropyridine-3-carboxylic acid as an off-white solid.
