Procedure

3 g (18.9 mM) of 2-chloro-3-nitropyridine and 5 g (70.3 mM) of cyclopropylmethylamine in 12 ml of tetrahydrofurane were refluxed under stirring for 1 h. Water was added and the aqueous layer was extracted with ethylacetate. The organic layer was washed with water and dried over anhydrous sodium sulfate. The solvent was removed under vacuum to give 3.5 g of N-(cyclopropylmethyl)-3-nitropyridin-2-amine as a yellow oil. Yield: 95.7%.
