A mixture of 4.05 g (10.0 mmol) N-(4-iodo-6-thiomorpholin-4-yl-pyridin-3-yl)-2,2-dimethyl-propionamide, 54 ml toluene, 16 ml 2 N sodium carbonate solution, 347 mg (0.3 mmol) tetrakis(triphenylphosphine)palladium(0), 67 mg (0.3 mmol) palladium(II) acetate and 1.50 g (11.0 mmol) o-tolylboronic acid was heated under argon at 80° C. for 18 h. After cooling to room temperature, the aqueous phase was separated and washed twice with ethyl acetate. The combined organic layers were washed with 50 ml brine, dried (sodium sulfate) and evaporated. Purification by flash-chromatography gave 3.57 g (quantitative) of the title compound as a light brown solid.
