Procedimiento

To a 25 mL round bottom in a drybox was added nitrosonium tetrafluoroborate (0.11 g, 0.95 mmol). Acetonitrile (2 mL) was added and the flask was cooled down to −30° C. A solution of 4-STYRYLPHENYLAMINE (0.17 g, 0.86 mmol) and BHT (0.19 g, 0.86 mmol) in acetonitrile (5 mL) was added dropwise via syringe. The reaction was allowed to warm to −5° C. over 20 min. Ether (10 mL) was then added and the precipitate was filtered. The title compound was purified by re-precipitating from acetonitrile (3 mL) with ether (15 mL) to yield 0.82 g (34%) of the desired compound.
