Versuchsvorschrift

4-Bromo-1-[2-(trimethylsilyl)ethoxy]methyl-1H-pyrrolo[2,3-b]pyridine (0.06 g, 0.0002 mol) and 1-(2-naphthylmethyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (0.074 g, 0.00022 mol) were combined in toluene (2.0 mL, 0.019 mol) and ethanol (1.0 mL, 0.017 mol), and then potassium carbonate (0.063 g, 0.00046 mol, in 1 mL water) was added. The reaction mixture was degassed with nitrogen, then tetrakis(triphenylphosphine)palladium(0) (0.02 g, 0.00002 mol) was added, sealed in a tube and heated to 120° C. in a microwave for 30 minutes. This was allowed to cool and then partitioned between ethyl acetate and brine. The organic layer was dried over magnesium sulfate and concentrated to give 4-[1-(2-naphthylmethyl)-1H-pyrazol-4-yl]-1-[2-(trimethylsilyl)ethoxy]methyl-1H-pyrrolo[2,3-b]pyridine 0.08 g, as an oily residue, LC/MS (M+H)+: 455.
