実験手順
Subsequently, to a suspension of (pyrrol-2-yl)methyl trimethylammonium iodide (7.59 g, 28.52 mmol) obtained above in acetonitrile (60 ml) was added triphenylphosphine (8.98 g, 34.2 mmol) with stirring, and the resulting mixture was stirred at 80° C. for 6 hours. After cooling, the reaction mixture was concentrated to about one-half of its initial volume, to which was added ethyl acetate (100 ml). The crystals precipitated were collected by filtration, washed with ethyl acetate and dried in vacuo to afford (pyrrol-2-yl)methyl trimethylphosphonium iodide (12.33 g, yield: 92%).
