Ethanol → 5-Cyano-2-hydroxybenzoic acid

Participants

Reaction Steps

Ethanol (10 mL) and tetrahydrofuran (10 mL) were added to 2-benzyloxy-5-cyanobenzoic acid benzyl ester (446 mg, 1.3 mmol) and 5% palladium on carbon (45 mg), and the mixture was hydrogenated at room temperature for 2 hours. After the insoluble matter was filtered off, the solvent was evaporated under reduced pressure to give the title compound (212 mg, 100.0%) as a white solid.
