Procedure
A mixture, of 1,1-dimethylethyl 4-(6-bromo-1H-indazol-3-yl)-1-piperazinecarboxylate (Intermediate 6, 660 mg) N-ethyl-4-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzamide (Intermediate 10, 598 mg) tetrakis(triphenylphosphine)palladium (25 mg) and aqueous sodium hydrogen carbonate (1M, 1.5 ml) in isopropanol (6 ml) was stirred at 150° C. for 20 min in a microwave oven. DCM and water were added and the organic phase was separated using a hydrophobic filter tube and concentrated under vacuum. The residue was purified by chromatography on a silica column eluting with a cyclohexane/ethyl acetate gradient to give the title compound (660 mg).
