Procedure

To the 3-(5-bromopyridin-3-yl)-3-[4-(7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]-pyrimidin-4-yl)-1H-pyrazol-1-yl]propanenitrile (0.130 g, 0.000248 mol) from Example 429 Step 2, in dry 1,4-dioxane (1.60 mL, 0.0205 mol) was added DIPEA (0.085 mL, 0.00049 mol). The solution was degassed with nitrogen, followed by addition of (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (0.007 g, 0.00001 mol), bis(dibenzylideneacetone)palladium(0) (0.0036 g, 0.0000062 mol), and benzenethiol (0.025 mL, 0.00025 mol). Again the solution was purged with nitrogen. The reaction mixture in a sealed tube was heated to reflux for 3 h. The reaction mixture was diluted with ethyl acetate, washed with water (2×), brine (1×), dried over magnesium sulfate, filtered, and the solvent was evaporated in vacuo. The crude product was triturated with hexane-ethyl acetate 9:1 to yield 3-[5-(phenylthio)pyridin-3-yl]-3-[4-(7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]propanenitrile (110 mg, 80%). LC/MS (M+H)+: m/z=554.2.
