Participants

Reaction Steps

The title compound was prepared in accordance with the general method of Example 1, from 2-chloro-3-fluoropyridine (42 mg, 0.32 mmol) and 2-(but-3-ynyl)-2H-benzo[d][1,2,3]triazole (50 mg, 0.29 mmol, Example 109(D)). Reaction time: 13 hours. The crude residue was purified by flash chromatography (DCM/MeOH 99:1) to yield 21 mg (80 mmol, 27%) of 2-(4-(3-fluoropyridin-2-yl)but-3-ynyl)-2H-benzo[d][1,2,3]triazole as a yellow solid.
