Procedimiento

A mixture of 6.17 g. (10.0 mmols.) of 1-benzyl-3-[2-benzyloxy-4-(1,1-dimethylheptyl)phenyl]-4-(3-phenylpropyl)-4-piperidinol, 2.0 g. of 10% palladium-on-carbon and 50 ml. of ethanol is stirred under one atmosphere of hydrogen for 2 hours. The reaction mixture is filtered through diatomaceous earth with ethyl acetate and the filtrate evaporated. The residue is purified via crystallization from ether-pentane to yield the title compound.
