実験手順

A mixture of 2-fluoro-5-pyridylmethyl bromide (9.5 g), 2-(nitroimino)imidazolidine (6.5 g), potassium carbonate (7.6 g) and acetonitrile (100 ml) was refluxed for 2 hours with stirring. After the reaction, the reaction mixture was cooled to room temperature, and cold water (100 ml) was added. The resulting crystals were collected by filtration and washed with ether to give slightly colored 1-(2-fluoro-5-pyridylmethyl)-2-(nitroimino)imidazolidine (6.0 g) as the desired compound.
