Hydrochloric Acid → Methyl 3-[(4-ethylphenyl)methyl]-4-hydroxybenzoate

Participants

Reaction Steps

The thus obtained methyl 3-[(4-ethylphenyl)hydroxy-methyl]benzoate (2.88 g, 10.0 mmol), 10% palladium carbon (200 mg), concentrated hydrochloric acid (0.5 mL) and methanol (15 mL) were mixed and stirred under a hydrogen atmosphere at room temperature for 14 hours. After filtration to remove the insoluble materials, the solvent was distilled off under reduced pressure and the resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=80:20) to give methyl 3-(4-ethylbenzyl)-4-hydroxybenzoate (2.38 g, 88%) as a colorless powder.
