実験手順

An amount of 4-(3-chloro-4-fluoro-phenylamino)-7-methoxy-6-nitro-quinoline-3-carbonitrile (9.9 g, 0.27 mmol) was combined with ammonium chloride (11.4 g, 0.21 mol), iron powder (8.9 g, 0.16 mol), methanol (200 mL), and water (50 mL), and heated at reflux for 2 hours. An additional amount of iron (1.0 g, 0.018 mol) and ammonium chloride (1.0 g, 0.019 mol) were added and the mixture was refluxed for an additional 3.5 hours. The reaction mixture was filtered hot and the residue was washed with boiling methanol to extract the product. The filtrate was evaporated to a slurry and stirred with saturated sodium bicarbonate solution and ethyl acetate. The layers were separated, and the organic layer was dried over magnesium sulfate and evaporated to dryness to give a green powder (7.8 g, 85%), which was used without further purification.
