Reaction Steps

To a solution of 6-(2-ethyl-5-fluoro-4-methoxy-phenyl)-1-(tetrahydro-pyran-2-yl)-3-trimethylstannanyl-1H-indazole (Preparation 18, 735 mg, 1.53 mmol) in toluene (6 mL) was added 2-iodo-1-(2-trimethylsilanyl-ethoxymethyl)-1,4,6,7-tetrahydro-imidazo[4,5-c]pyridine-5-carboxylic acid tert-butyl ester (Preparation 22, 805 mg, 1.68 mmol), copper (1) iodide (60 mg, 310 μmol) and tetrakis(triphenylphosphine) palladium(0) (173 mg, 150 μmol). The reaction mixture was degassed with nitrogen, heated at 100° C. for 18 hours, cooled to room temperature and concentrated in vacuo. The residue was purified by column chromatography on silica gel eluting with 20% EtOAc in toluene to give the title compound as a foam (801 mg) in a 74% yield.
