Versuchsvorschrift

In a vial under argon (1R,2S)-2-amino-1-phenylpentan-1-ol hydrochloride (91b, 46 mg, 0.21 mmol), 1-(4-fluorophenyl)-5-iodo-1H-indazole (87 mg, 0.26 mmol), copper(I)iodide (8.12 mg, 0.04 mmol) and cesium carbonate (278 mg, 0.85 mmol) were mixed in butyronitrile (0.6 mL). The vial was sealed and heated to 125° C. for 16 h. The mixture was filtered through celite. The celite was washed with ethyl acetate. The collected organic phases were evaporated and the crude product was purified by preparative HPLC. The pure fractions were collected, ethyl acetate and a saturated sodium carbonate were added and the mixture was shaken. The organic layer was separated and the water layer was washed twice with ethyl acetate. The combined organic layers were dried over sodium sulphate and finally evaporated to give the pure product.
