Versuchsvorschrift

A stirred mixture of 6-bromo-2-[2-(3,5-dimethoxyphenyl)ethyl]-5-(phenylsulfonyl)-5H-pyrrolo[2,3-b]pyrazine (from Example 1, Step 4, 40.0 mg, 79.7 μmol), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) complexed with dichloromethane (1:1) (3.25 mg, 3.98 μmol), tert-butyl[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazol-1-yl]acetate (24.5 mg, 79.6 μmol), and potassium phosphate (33.8 mg, 0.159 mmol) in water (0.5 mL)/1,4-dioxane (1.0 mL) was heated at 88° C. After 1 hour, the reaction was quenched with saturated aqueous NH4Cl, extracted with methylene chloride. The combined organic layers were dried over MgSO4, and then concentrated. The residue was dissolved in methylene chloride (1 mL) and trifluoroacetic acid (1 mL) was added at ambient temperature. After 2 hours, the volatiles were removed under vacuum to afford the desired product (40 mg, 92%). LCMS calculated for C27H26N5O6S (M+H)+: m/z=548.2. Found: 548.2.
