Procedure

The title compound was prepared in accordance with the general method of Example 1, from 6-bromo-pyridin-2-ylamine (60 mg, 0.35 mmol) and 2-but-3-ynyl-4,6-difluoro-2H-benzo[d][1,2,3]triazole (72 mg, 0.35 mmol, Example 135(B)). Reaction time: 3 hours. The crude residue was purified by flash chromatography (DCM/AcOEt 1:1) to yield 65 mg (0.22 mmol, 63%) of 6-(4-(4,6-difluoro-2H-benzo[d][1,2,3]triazol-2-yl)but-1-ynyl)pyridin-2-amine as a brown solid.
