Reaction Steps

Under an argon atmosphere 44 mg (0.34 mmol) 3-trimethylsilanyl-prop-2-yn-1-ol, 50 μL TEA, 13 mg 1,1′-bis(diphenylphosphine)ferrocene dichloropalladium (II) and 3 mg (20 μmol) copper(I) iodide were added to 0.10 g (0.17 mmol) 1-[2′-(5-fluoro-2,3-dihydro-indole-1-carbonyl)-5′-iodo-3,4,5,6-tetrahydro-2H-[1,4′]bipyridinyl-4-yl]-1,3-dihydro-imidazo[4,5-b]pyridin-2-one in 4.0 mL 1,4-dioxane. Then 0.36 mL (0.36 mmol) of a 1 molar tetrabutylammonium fluoride solution in THF were added dropwise and the mixture was then stirred for 4 h at 80° C. The reaction mixture was mixed with water and the precipitate formed was suction filtered. The precipitate was stirred in 6 mL DMF and suction filtered. The filtrate was purified by preparative HPLC-MS. The product-containing fractions were combined and freeze-dried.
