실험 절차

2-amino-3-nitro-6-(phenylmercapto)pyridine was prepared by heating 2-amino-6-chloro-3-nitropyridine (84.0 g, 0.484 mol) and sodium thiophenolate (Fluka) (72.0 g, 0.545 mol) in 2-propanol (1500 mL) under reflux for 2 hours. After cooling to room temperature the suspension was diluted with water (100 ml), the solid was collected by vacuum filtration, washed with water and 2-propanol, and dried at 50° C. under vacuum to give 109.1 g (95% yield) of 2-amino-3-nitro-6-(phenylmercapto)pyridine, m.p. 148-152° C.).
