2-(3,6-dihydro-2H-pyran-4-yl)-4,6-dimethylphenol → 2,4-dimethyl-6-(tetrahydro-2H-pyran-4-yl)phenol

Participants

Reaction Steps

2-(3,6-dihydro-2H-pyran-4-yl)-4,6-dimethylphenol (Compound 6-17) (234 mg, 1.14 mmol) was dissolved in methanol. Palladium carbon (92 mg, 40 wt %) was added thereto, followed by stirring under hydrogen balloon for 24 hours. After the completion of the reaction, the reaction mixture was filtered through Celite. The filtrate was concentrated under reduced pressure. The residue was purified by column chromatography (silica gel; hexane/ethyl acetate, 9/1) to obtain 2,4-dimethyl-6-(tetrahydro-2H-pyran-4-yl)phenol (156 mg, 66%) as a white solid.
