Versuchsvorschrift
The title compound was prepared in accordance with the general method of Example 108(B), from 7-chloro-2-(4-trimethylsilanyl-but-3-ynyl)-2H-indazole and 7-chloro-1-(4-trimethylsilanyl-but-3-ynyl)-1H-indazole (250 mg, 0.90 mmol). The crude residue was purified by flash chromatography (cyclohexane/AcOEt 9:1) to yield 44 mg (0.21 mmol, 23%) of 2-(but-3-ynyl)-7-chloro-2H-indazole as an orange oil.
