The condensation of 3-(methylsulfonyl)bromobenzene (I) with diethyl(3-pyridyl)borane (II) by means of Pd(PPh3)4, KOH and tetrabutylammonium iodide (TBAI) gives 3-[3-(methylsulfonyl)phenyl]pyridine (III), which is hydrogenated with H2 over PtO2 in methanol, yielding the racemic piperidine (IV). The optical resolution of (IV) with (+)-tartaric acid affords the (S)-enantiomer (V), which is alkylated by reductocondensation with propionic aldehyde and NaBH(O-tBu)3 in dichloroethane and HOAc.
