2-Bromo-6-(difluoromethyl)pyridine → 2-(4-(6-(difluoromethyl)pyridin-2-yl)but-3-ynyl)-2H-benzo[d][1,2,3]triazole

Participants

Reaction Steps

The title compound was prepared in accordance with the general method of Example 1, from 2-bromo-6-(difluoromethyl)-pyridine (121 mg, 0.58 mmol) and 2-(but-3-ynyl)-2H-benzo[d][1,2,3]triazole (100 mg, 0.58 mmol, Example 109(D)). Reaction time: 2 hours. The crude residue was purified by preparative chromatography plate (DCM/MeOH 99:1) to yield 15 mg (49 μmol, 8%) of 2-(4-(6-(difluoromethyl)pyridin-2-yl)but-3-ynyl)-2H-benzo[d][1,2,3]triazole as a white solid (M.P.: 101.8-102.9° C.).
