Participants

Reaction Steps

A mixture of 174 mg (0.32 mmol, 1 eq) of 4-(2,4-bis(benzyloxy)-5-fluorophenyl)piperidine-1-carboxylic acid phenylamide in 1 ml of ethyl acetate and of 2 ml of methanol in the presence of 51 mg (30% by mass) of palladium-on-charcoal at 10% is stirred at ambient temperature under atmospheric hydrogen pressure for 8 hours. The reaction medium is filtered through filter paper and the filtrate is evaporated off. The residue is chromatographed on silica gel, elution being carried out with 30/70 heptane/ethyl acetate. 83 mg of 4-(5-fluoro-2,4-dihydroxyphenyl)piperidine-1-carboxylic acid ((S)-1-phenylethyl)amide are obtained.
