Versuchsvorschrift

To tert-butyl 3-(7-(bis((2-(trimethylsilyl)ethoxy)methyl)amino)-3-iodopyrazolo[1,5-a]pyrimidin-5-yl)-8-azabicyclo[3.2.1]octane-8-carboxylate (2 g, 2.7 mmol) in dioxane (22 mL) and H2O (5.5 mL) was added 2-phenyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (1.2 g, 4.1 mmol), PdCl2(dppf).CH2Cl2 (0.3 g, 0.3 mmol) and K2CO3 (1.2 g, 8.2 mmol). The reaction was heated at 100° C. for 15 hours, at which time LC/MS analysis confirmed full consumption of starting material. On cooling, H2O (40 ml) and EtOAc (100 mL) were added and organics were extracted with EtOAc (2×75 ml), dried (Na2SO4) and concentrated in vacuo to crude. Gradient column chromatography on silica eluting with 0 to 50% EtOAc/hexanes gave tert-butyl 3-(7-(bis((2-(trimethylsilyl)ethoxy)methyl)amino)-3-(6-phenylpyridin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)-8-azabicyclo[3.2.1]octane-8-carboxylate.
