Reaction Steps

6-Bromo-2-(2-fluoro-phenyl)-4-pyrrolo[3,2-c]pyridin-1-yl-quinazoline from step E (0.1 g, 0.23 mmol) was dissolved in tetrahydrofuran (5 ml) in a 50 ml round bottomed flask. Cesium carbonate (0.11 g, 0.35 mmol), Xanphos (0.007 g, 0.002 mmol) and methyl-carbamic acid tert-butyl ester (0.045 g, 0.35 mmol) was then added. The mixture was degassed for 5 mins and tris (dibenzylidineacetone)dipalladium(0) (0.005 g, 0.005 mmol) was added. The resulting solution was then magnetically stirred and the heated to 80° C. for 3 hrs. Water was added and compound extracted into ethyl acetate, dried over sodium sulfate and concentrated in rotary evaporator to yield desired title compound (0.066 g, 58%). MS (ES) 470.1 (M+H)+
