The title compound was prepared in accordance with the general method of Example 1, from 2-bromo-6-(fluoromethyl)-pyridine (0.12 g, 0.61 mmol) and 2-but-3-ynyl-4-fluoro-2H-indazole (104 mg, 0.5 mmol). Reaction time: 3 hours. The crude residue was purified by flash chromatography (cyclohexane/AcOEt 3:2) to yield 60 mg (0.20 mmol, 36%) of 4-fluoro-2-(4-(6-(fluoromethyl)pyridin-2-yl)but-3-ynyl)-2H-indazole as a brown solid.
