Reaction Steps

4-[1,2,3]Triazol-1-yl-benzonitrile (0.105 g, 0.6 mmol) and dry THF (6 ml) and a magnetic stirrer were placed in a flask. The flask was flushed with argon and kept under an inert atmosphere and cooled to −78° C. At this temperature, tert-BuLi (0.36 ml, 1.7M, 0.6 mmol) was added dropwise during 1-2 minutes. The mixture was stirred at this temperature for 15 minutes and Bu3SnCl (0.19 g, 0.6 mmol) was added during 1 minute, and the mixture was then allowed to slowly reach RT. The crude mixture was directly purified on silica (heptane:EtOAc 4:1) giving 0.12 g (43%) of the title stannane.
