Procedure

6-Bromo-2-(2-fluoro-phenyl)-4-pyrrolo[3,2-c]pyridin-1-yl-quinazoline from Step E, Example 3 (0.1 g, 0.23 mmol) was dissolved in tetrahydrofuran (5 ml). Sodium carbonate (0.075 g, 0.7 mmol) and benzamide-3-boronic acid (0.040 g, 0.24 mmol) was added followed by tetrakis(triphenylphosphine)palladium(0) (0.005 g, 0.004 mmol) after degassing for 5 mins. Water (0.5 ml) was added drop wise and the mixture was magnetically stirred and heated to 80° C. for 4 hrs. Water was added and product extracted with ethyl acetate. The ethyl acetate layer was dried and evaporated in a rotary evaporator and the residue further purified using a HPLC reverse phase column using an acetonitrile and water gradient containing 0.1% trifluoroacetic acid to yield the title compound (0.028 g, 25%). MS (ES) 460.0 (M+H)+
