실험 절차

Ethyl 6-chloro-5-nitronicotinate (1.00 g, 4.33 mmol) prepared according to A. H. Berrie et al. (J. Chem. Soc. 1951, 2590) was dissolved in DMSO (2 mL) and cyclohexylamine (0.54 g, 5.4 mmol) was added. The mixture was stirred for 1 h at room temperature, diluted with water and the yellow precipitate collected by filtration. The product was washed with water and dried (0.95 g, 74% yield).
