Versuchsvorschrift

A mixture of 5-bromo-3-iodo-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-indazole (906 mg, 0.00200 mol), (2-amino-1-phenyl-1H-benzoimidazol-5-yl)methanol (435 mg, 0.00182 mol), copper(I) iodide (110 mg, 0.00056 mol), trans-N1,N2-dimethylcyclohexane-1,2-diamine (160 mg, 0.0011 mol) and potassium phosphate (772 mg, 0.00364 mol) in tetrahydrofuran (19.4 mL) was stirred under argon sparging until a greenish suspension formed. The mixture was then microwaved at 140° C. for 3 hours. The reaction mixture was diluted with ethyl acetate and washed with 5% citric acid, saturated sodium bicarbonate, brine, dried over magnesium sulfate and concentrated. The residue was purified by flash chromatography using 0-100% ethyl acetate-hexanes. The product was taken up in ethyl acetate, washed with 1N HCl to remove residual copper and rechromatograped to give 75 mg of product.
