Versuchsvorschrift
The title compound was prepared in accordance with the general method of Example 1, from 1-(6-bromo-pyridin-2-yl)-ethanone (500 mg, 2.66 mmol) and 2-but-3-ynyl-2H-benzo[d][1,2,3]triazole (455 mg, 2.66 mmol, Example 109(D)). Reaction time: 3 hours. The crude residue was purified by flash chromatography (cyclohexane/AcOEt 4:1) to yield 380 mg (1.36 mmol, 51%) of 1-[6-(4-benzotriazol-2-yl-but-1-ynyl)-pyridin-2-yl]-ethanone as a white solid.
