Versuchsvorschrift

4-Chloro-7-(3,5-dimethyl-4-isoxazolyl)-6-(methyloxy)-3-nitroquinoline (for a preparation see Intermediate 8) (1.06 g, 3.18 mmol) was dissolved in NMP (5 ml), then DIPEA (0.56 ml, 3.18 mmol) and (tetrahydro-2H-pyran-4-yl)methanamine (0.75 g, 6.51 mmol) were added at room temperature. The reaction mixture immediately changed colour and within 5 minutes, a thick yellow precipitate was formed. The mixture was stirred for 20 min, then diluted with water (30 ml) and stirred for 10 min. The precipitate was collected by filtration and washed with water (2×20 ml), then dried in vacuo to give 7-(3,5-dimethylisoxazol-4-yl)-6-methoxy-3-nitro-N-((tetrahydro-2H-pyran-4-yl)methyl)quinolin-4-amine (1.22 g, 2.96 mmol, 93% yield) as a bright yellow solid. LCMS (formate) Rt 0.88 min, MH+ 413
