Reaction Steps

In a 25 ml round-bottomed flask, 1.23 g of {(R)-1-benzyl-2-[4-(2,4-bis(benzyloxy)phenyl)piperidin-1-yl]-2-oxoethyl}carbamic acid benzyl ester are dissolved in 15 ml of methanol and also 15 ml of ethyl acetate in the presence of 0.25 g of palladium-on-charcoal at 10%. The reaction mixture is stirred for 18 hours under a hydrogen atmosphere. The reaction mixture is filtered. The residue is chromatographed on silica gel (95/5 dichloromethane/methanol). 0.625 g of (R)-2-amino-1-[4-(2,4-dihydroxyphenyl)piperidin-1-yl]-3-phenylpropan-1-one is obtained. Yield=64%.
