実験手順

2-chloro-3-chloromethyl-5-methylpyridine (1.3 g, 0.0076 moles) was added to a well-stirred material comprising 2-nitroimino-1, 3-diazacyclopentane (1.18 g, 0.00912 moles), potassium carbonate (1.16 g, 0.0083 moles), cesium chloride (0.04 g, 0.00024 moles) in acetonitrile (20 ml) solvent at room temperature. The reaction mixture was refluxed for 8 hours. The solvent was removed under reduced pressure and the mass diluted with water (25 ml). The mass was then extracted with methylene chloride (2×50 ml) and the layers were separated. Organic layer was dried over sodium sulphate and solvent removed under reduced pressure. The residue thus obtained was subjected to chromatographic purification on silica gel to give 1-(2-chloro-5-methyl-3-pyridylmethyl)2-nitroiminoimidazolidine in 90% yield.
