Acetic Acid → Methyl 5-(2-cyanoethyl)-6-methoxynicotinate

Participants

Reaction Conditions

Reaction Steps

To a mixture of methyl 5-(2-cyanovinyl)-6-methoxynicotinate (1.02 g), acetic acid (20 ml) and methanol (20 mL) was added 10% palladium-carbon (504 mg), and the mixture was stirred under a hydrogen atmosphere at 70° C. for 40 hr. The reaction mixture was filtered, and the filtrate was diluted with THF and ethyl acetate. The diluted solution was washed with saturated aqueous sodium hydrogen carbonate solution and saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (589 mg) as white crystals.
