Reaktionsschritte

The subtitle compound was prepared analogous to the method described in Example 6 (step 6a). Starting from the hydrochloride salt of (1R,2S)-2-amino-1-(3-methoxyphenyl)propan-1-ol (6b) (0.88 g, 4.04 mmol), 1-(4-chlorophenyl)-5-iodo-1H-indazole (1.720 g, 4.85 mmol), CuI (0.154 g, 0.81 mmol) and cesium carbonate (3.95 g, 12.13 mmol) in butyronitrile (14 mL) stirred at +110° C. for 16 h. Work up and final purification by HPLC was followed by extraction of product into EtOAc from basic water solution, evaporation of solvents gave the subtitle compound as a sticky oil. Yield 490 mg (29%)
