To a solution of 5-bromo-6-chloro-3-(1-BOC-2-(S)-pyrrolidinylmethoxy)pyridine (from Example 23a, 500 mg, 1.28 mmol) in toluene (10.0 mL) was added 3-pyridinyltributyltin (564 mg, 1.5 mmol) and tetrakis(triphenylphosphine)palladium(0) (45 mg, 0.039 mmol). After being refluxed overnight, the resulting mixture was cooled to room temperature. Solvent was removed and the residue was chromatographed on a silica gel column, eluting with hexane/EtOAc 2:1 and 1:1 to afford an oil (428 mg, 86%).
