実験手順
The mixture of 4-chloro-7-(3,5-dimethyl-4-isoxazolyl)-6-(methoxy)-3-quinolinecarboxamide (for a preparation see intermediate 40, 6 g, 18 mmol) was reacted with (1R)-1-(2-pyridinyl)ethanamine (2 eq., 4.43 g, 36 mmol) in CH3CN (100 ml) and was stirred at 110° C. for 4 h. The reaction mixture was concentrated in vacuo. The residue was partitioned between water and DCM. The organic layer was dried over Na2SO4 and concentrated to dryness to give 7-(3,5-dimethyl-4-isoxazolyl)-6-(methoxy)-4-{[(1R)-1-(2-pyridinyl)ethyl]-amino}-3-quinolinecarboxamide which was used in the next step without purification. The carboxamide intermediate (6 g) was treated with an excess of [bis(trifluoroacetoxy)iodo]benzene (19.35 g, 45 mmol) in CH3CN (100 ml), the mixture was stirred at room temperature overnignt. The reaction mixture was concentrated in vacuo, the resulting residue was dissolved in DCM and washed with water. The crude product was purified by flash chromatography on silica gel (DCM/MeOH, 95:5), the resulting compound was dissolved in DCM and precipitated from diethylether to give the title compound as an off-white powder (2.5 g, 33%)
