YieldReaction ConditionsOperation in experiment
49% With hydrogenchloride; tin(ll) chloride; In water; at 80 - 100℃; for 0.5h; 5-Chloro-3-nitropyridin-2-amine (2000.0 mg, 11.52 mmol) and SnCl2 (8740.0 mg, 46.09 mmol) were added in conc. HCl (20.0 mL) and then stirred at 80-100 C. for 0.5 hour. The reaction mixture was neutralized with saturated 1N NaOH aqueous solution (pH=7), and it was then extracted with EtOAc (200.0 mL). The organic layer was washed with brine, dried over anhydrous Na2SO4, filtered and then distilled under reduced pressure. The residue was purified by column chromatography (n-Hex:EtOAc=90:10) on silica. The fractions containing the product were collected and evaporated to obtain ivory solid compound of 5,6-dichloropyridin-2,3-diamine (1000.0 mg, 49%).
