Procedure
The title compound was prepared in accordance with the general method of Example 1, from 2-bromopyridine (36 mg, 0.23 mmol) and 2-but-3-ynyl-7-chloro-2H-indazole (44 mg, 0.21 mmol). Reaction time: 1 day. The crude residue was purified by flash chromatography (DCM/MeOH 98:2) to yield 11 mg (41 μmol, 19%) of 7-chloro-2-(4-(pyridin-2-yl)but-3-ynyl)-2H-indazole as a brown oil.
