Procedure
The title compound was prepared from 3-formyl-pyridine-2-carbonitrile (26 mg, 198 μmol) and 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, 132 μmol) using the method of Example 22. The crude material was purified by HPLC Method A to afford 14.9 mg of the title compound.
