Tetrakis(triphenylphosphine)palladium(0) (52 mg, 0.05 mmol) was dissolved in 8 ml toluene. 4-Chloro-7-iodo-2-methyl-thiazolo[4,5-c]pyridine (280 mg, 0.90 mmol) (Example B), 3-pyridineboronic acid (133 mg, 1.08 mmol), 2M sodium carbonate (2.70 ml, 5.4 mmol) and 2 ml ethanol were added and the mixture stirred at 80° C. for 6 hrs. The reaction mixture was extracted with water and two times ethyl acetate. The organic extracts were washed with water and brine, dried with sodium sulfate, filtered and evaporated. The crude product was purified by flash chromatography on silica gel (heptane/ethyl acetate 9:1->0:100 gradient). The desired compound was obtained as a light yellow solid (100 mg, 42%), MS: m/e=263.1 (M+H+).
