4-(2,3-Dihydro-pyrrolo[3,2-c]pyridin-1-yl)-3-fluoro-2-iodo-quinoline from step B (0.025 g, 0.063 mmol) was dissolved in tetrahydrofuran (5 ml) in a 25 ml round bottomed flask equipped with a magnetic stirrer. Sodium carbonate (0.06 g, 0.1 mmol) was added followed by 5-chlorothiophene-2-boronic acid (0.019 g, 0.08 mmol) and the mixture was degassed for 5 mins. Tetrakis(triphenylphosphine)-palladium(0) (5 mg, 5 mol %) was added followed by 0.5 ml water and the reaction mixture was heated to 80° C. for 4 hrs. The compound was extracted with ethyl acetate, dried and concentrated in vacuo. The title compound was purified by HPLC over a reverse phase column using a gradient of acetonitrile and water containing 0.1% trifluoroacetic acid to yield desired compound (0.012 g, 52%). MS (ES) 482.4 (M+H)+
