ethyl 4-(3-benzyloxy-5-fluorophenyl)-3,4,5,6-tetrahydro-2H-pyran-4-carboxylate → 4-(3-Fluoro-5-hydroxyphenyl)-3,4,5,6-tetrahydro-2H-pyran-4-carboxylate Ethyl

Participants

Reaction Steps

A mixture of ethyl 4-[3-(benzyloxy)-5-fluorophenyl]-3,4,5,6-tetrahydro-2H-pyran-4-carboxylate (2.70 g, 7.5 mmol) and 10% palladium on activated carbon (0.27 g) in ethanol (100 ml) was stirred under a hydrogen atmosphere for 3.25 hr. Catalyst was removed by filtration and evaporation of the filtrate gave the titled compound as a colorless liquid (2.01 g, quantitative yield).
