실험 절차

To a solution of 4-(4-chloro-6-methoxy-3-nitroquinolin-7-yl)-3,5-dimethylisoxazole (Manchester Organics) (20 g, 59.9 mmol) in 1,4-dioxane (200 ml) was added 1-methoxypropan-2-amine (31.6 ml, 300 mmol) and the reaction mixture heated at 70° C. for 1.5 h. The solvent was removed under reduced pressure and the resulting solid partitioned between ethyl acetate (3×750 ml) and water (750 ml). The organic layers were combined, dried (hydrophobic frit) and evaporated under reduced pressure to give 7-(3,5-dimethylisoxazol-4-yl)-6-methoxy-N-(1-methoxypropan-2-yl)-3-nitroquinolin-4-amine (25.8 g), which was used without further purification in the subsequent step.
