Reaction Steps

The title compound was prepared in accordance with the general method of Example 1, from 2-bromo-pyridine (76 mg, 0.48 mmol) and 2-but-3-ynyl-4-nitro-2H-benzo[d][1,2,3]triazole (95 mg, 0.44 mmol). Reaction time: 3 hours. The crude residue was purified by flash chromatography (DCM/MeOH 99:1) to yield 40 mg (0.14 mmol, 31%) of 4-nitro-2-(4-(pyridin-2-yl)but-3-ynyl)-2H-benzo[d][1,2,3]triazole as an orange oil.
