Participants

Reaction Steps

The title compound was prepared in accordance with the general method of Example 1, from 2-bromo-pyridine (25 mg, 0.16 mmol) and 2-(but-3-ynyl)-4-chloro-2H-benzo[d][1,2,3]triazole (30 mg, 0.15 mmol). Reaction time: 3 hours. The crude residue was purified by flash chromatography (DCM/MeOH 99:1) to yield 12 mg (42 μmol, 29%) of 4-chloro-2-(pyridin-2-yl)but-3-ynyl)-2H-benzo[d][1,2,3]triazole as an orange solid.
