Versuchsvorschrift

A solution of 6-bromo-1H-indole-3-carbonitrile (400 mg, 1.81 mmol), 2-(tributylphosphoranylidene)acetonitrile (655 mg, 2.71 mmol) and benzyl alcohol (282 μL, 2.71 mmol) in toluene (5 mL) was heated at 75° C. overnight and concentrated. The residue was purified by flash chromatography on silica (IntelliFlash Varian 971-FP), eluting with 30% heptanes in ethyl acetate to provide the title compound. LCMS: 312.4 (M+H)+.
