Reaction Steps

144.7 mg of 2-[1-(2-fluoro-4-iodobenzyl)-1H-indazol-3-yl]-5-methoxy-N-(pyridin-4-yl)pyrimidin-4-amine (2-201, 0.262 mmol, 1 eq.), 6.02 mg of (1E,4E)-1,5-diphenylpenta-1,4-dien-3-one-palladium (2:1) (0.01 mmol, 0.04 eq.), 2.0 mg of copper (I) iodide (0.01 mmol, 0.04 eq.), and 13.7 mg of triphenylphosphane (0.052 mmol, 0.2 mmol) were suspended in 2.6 ml of dry N,N-diethylethanamine and purged with nitrogen. Then 3.86 ml of ethynyl(trimethyl)silane (1.57 mmol, 6 eq.) were added and the reaction mixture was stirred at 60° C. for 18 hours. The mixture was concentrated under vacuo. The crude product was used without further purification in step 2.
