A practical synthesis of 2-benzenesulfonylpyridine, 1, is described which is a key starting material for the manufacture of an investigational new drug candidate at Eli Lilly and Company. An optimized green chemical process was developed which features a novel tandem SNAr/oxidation under mild conditions to produce the target sulfone, 1, in 86% yield and>99% purity. In addition, this novel, environmentally friendly methodology was found to be general for the synthesis of substituted aromatic pyridyl sulfides and sulfones.
