Acetic Acid → 6'-Methyl-2,3'-bipyridine-2'-carboxylic acid

Participants

Reaction Steps

6′-Methyl-[2,3′-bipyridine]-2′-carbonitrile (0.87 g, 4.46 mmol) and NaOH (1.87 g, 46.8 mmol) were dissolved in methanol (3 mL) and stirred at reflux overnight. The reaction was cooled to rt, diluted with more methanol (5 ml), and acidified with AcOH to pH 4-5. The solvent was removed in vacuo to obtain the crude which was purified by silica gel chromatography (0˜100% DCM/EtOAc) to yield the title compound as a clear oil (0.9 g, 94%).
