Versuchsvorschrift

A mixture of N-ethyl-3-fluoro-5-(3-iodo-1H-indazol-6-yl)-4-methylbenzamide (Intermediate 19, 2.34 g), 1,1-dimethylethyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3,6-dihydro-1(2H)-pyridinecarboxylate (1.71 g), aqueous sodium hydrogen carbonate (1M, 11.1 ml) and tetrakis(triphenylphosphine)palladium(0) (129 mg) in isopropanol (10 ml) was divided into three portions then stirred in sealed vials at 150° C. for 25 min in a microwave oven. The reaction mixtures were combined, the solvent was removed under vacuum and the residue was partitioned between ethyl acetate and water. The organic layer was separated using a hydrophobic filter tube, the solvent was evaporated and the residue was purified by chromatography on a silica column eluting with an ethyl acetate:cyclohexane gradient, to give the title compound as a yellow foam (1.76 g).
