Reaction Steps

To a microwave vial was added 8-Bromo-2-[2-(2,4-difluoro-phenyl)-2H-[1,2,4]triazol-3-yl]-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene (0.300 g, 0.000650 mol) and potassium acetate (0.1915 g, 0.001951 mol) in acetonitrile (1 mL, 0.02 mol) and water (2 mL, 0.1 mol). The reaction was thoroughly degassed and purged with N2 for 5 minutes. A solution of 1-[2-(Tetrahydro-pyran-2-yloxy)-ethyl]-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-pyrazole (0.2724 g, 0.0008455 mol) in acetonitrile (1 mL, 0.02 mol) was added, followed by tetrakis(triphenylphosphine)palladium(0) (0.07515 g, 6.504E-5 mol;) and the vial was sealed immediately. The reaction was heated to 140° C. for 20 minutes in the microwave. The mixture was diluted with methylene chloride and filtered through celite. Saturated NH4Cl was added and the mixture was extracted 3 times with methylene chloride. The organic layers were combined, dried with MgSO4 and concentrated. The crude was dissolved in methylene chloride (7 mL, 0.1 mol) and hydrogen chloride (4N in dioxoane, 0.38 mL, 0.001517 mol) was added dropwise. The reaction was stirred at room temperature for 1 hour.
