Reductive amination of 2,5-dimethyl-2-phenylhex-4-enal (X) with methylamine and NaBH3 gives the expected secondary amine as a racemic mixture that is separated by means of mandelic acid, yielding the desired isomer (XI). The sulfonylation of the resulting amine (XI) with benzenesulfonyl chloride (XII) provided sulfonamide (XIII). Dihydroxylation with N-methylmorpholine-N-oxide in the presence of a catalytic amount of osmium tetroxide gave rise to diol (XIV), which was oxidatively cleaved to aldehyde (XV) by means of sodium periodate. Finally, reductive condensation between aldehyde (XV) and piperidine (VI) furnished the title compound.
