To a 0° C. solution of 7.0 mmols. of 3-phenylpropylmagnesium bromide in 7 ml. of tetrahydrofuran is slowly added a solution of 2.48 g. (5.0 mmols.) of 1-benzyl-3-[2-benzyloxy-4-(1,1-dimethylheptyl)phenyl]-4-piperidone in 10 ml. of tetrahydrofuran. The resultant mixture is stirred for one hour and is then added to 250 ml. of saturated ammonium chloride-250 ml. ether. The ether phase is dried over magnesium sulfate and evaporated. The residue is purified via column chromatography on 200 g. of silica gel eluted with 50% ether-cyclohexane to yield the title compound.
