5-Iodo-1-(3-pyridinyl)indazole (750 mg, 2.3 mmole), 2-Amino-1-[6-methoxypyridin-3-yl]propan-1-ol (410 mg, 2.2 mmol), copper(I)iodide (42 mg, 0.22 mmol) and caesium carbonate (1.45 g, 4.5 mmole) were suspended in butyronitrile (2.4 mL) and toluene (4.8 mL). The reaction vessel was capped and the mixture was stirred at 130° C. for 20 hours. Then the solvent was removed i.vac., and the product purified by chromatography on silica gel. Yield 254 mg (3 0%) as a racemic mixture of two diastereomeres.
