Procedure

To a solution of 5-ethyl-2-fluoro-4-[3-(4,5,6,7-tetrahydro-1H-imidazo[4,5-c]pyridin-2-yl)-1H-indazol-6-yl]-phenol trihydrobromide salt (Preparation 25, 50 mg, 80 μmol) in DMF (1 mL), was added 6-cyano-nicotinoyl chloride (Preparation 46, 17 mg, 96 μmol), and DIPEA (56 μL, 320 μmol). The reaction mixture was stirred at room temperature for 72 hours and then saturated aqueous sodium hydrogen carbonate solution (5 mL) was added. The resulting solid was collected by filtration and washed with further saturated aqueous sodium hydrogen carbonate solution. The crude material was purified by reverse phase chromatography (Method C) to afford 6.9 mg of the title compound.
