Reaction Steps

The title compound was prepared in accordance with the general method of Example 1, from 2-bromopyridine (42 mg, 0.27 mmol) and 2-but-3-ynyl-4-chloro-2H-indazole (50 mg, 0.24 mmol). Reaction time: 8 hours. The crude residue was purified by flash chromatography (cyclohexane/AcOEt 1:1) to yield 12 mg (43 μmol, 17%) of 4-chloro-2-(4-(pyridin-2-yl)but-3-ynyl)-2H-indazole as a brown solid.
