Reaction Steps

To a microwave vial was added N-(5-bromo-2-(2,5-dimethyl-1H-pyrrol-1-yl)-6-methylpyrimidin-4-yl)-N-(pyrrolidin-1-yl)acrylamide (2.0 g, 4.95 mmol) silver carbonate (2.73 g, 9.89 mmol) and anhydrous THF (100 ml). The reaction suspension was bubbled in nitrogen for 2 mins and then added the palladium tetrakis tert-(triphenylphosphine) (286 mg, 0.25 mmol). After stirring at 70° C. oil bath for 3 h, the reaction mixture was cooled to R.T. and diluted with 20 ml of brine. After stirring at R.T. for 5 mins, the reaction mixture was filtered through a celite pad. The cake was washed with ethyl acetate. The layers were separated. The organic layer was washed with brine 20 ml, dried with potassium carbonate, filtered and concentrated under reduced pressure. The resulting residue was purified by column chromatography eluted with 40% etoac:hex to give the titled compound weighted 480 mg 30%
