Procedure

The title compound was prepared in accordance with the general method of Example 1, from 2-bromopyridine (42 mg, 0.26 mmol) and 2-(but-3-ynyl)-4,5-difluoro-2H-benzo[d][1,2,3]triazole (50 mg, 0.24 mmol). Reaction time: 13 hours. The crude residue was purified by flash chromatography (DCM/MeOH 99:1) to yield 41 mg (0.14 mmol, 60%) of 4,5-difluoro-2-(4-(pyridin-2-yl)but-3-ynyl)-2H-benzo[d][1,2,3]triazole as a yellow solid.
