Reaction Steps

The subtitle compound was prepared analogous to the method described in Example 19 (step 19a). (1R,2S)-2-amino-1-(naphthalen-2-yl)propan-1-ol hydrochloride (238 mg, 1.00 mmol), 1-(4-fluorophenyl)-5-iodo-1H-indazole (406 mg, 1.20 mmol), Cesium carbonate (979 mg, 3.00 mmol) and copper(I) iodide (38.1 mg, 0.20 mmol) in Butyronitrile (3 mL) was heated for 19 h at +125° C. in a sealed reaction tube flushed with Argon. After final purification by HPLC the obtained material was isolated as a brownish coloured hydrochloride salt from tert-butylmethylether/HCl.
