Versuchsvorschrift

The tert-butyl 4-(5,7-difluoro-3-methyl-4-(5-morpholinopyridin-3-ylamino)-quinolin-2-yl)piperazine-1-carboxylate (32 mg, 0.059 mmol) was dissolved in DCM (1.0 mL) and cooled to 0° C. The trifluoroacetic acid (1.00 mL, 13.0 mmol) was then added and the reaction mixture was allowed to slowly warm to rt over a period of 1 h. The reaction was then cond to dryness. The crude TFA salt was treated with satd sodium bicarbonate solution. The organic layer was dried over sodium sulfate and the filtrate was cond to give 5,7-difluoro-3-methyl-N-(5-morpholinopyridin-3-yl)-2-(piperazin-1-yl)quinolin-4-amine. 1H NMR (CDCl3) δ ppm 7.85 (1H, d, J=2.5 Hz), 7.63 (1H, d, J=2.2 Hz), 7.23 (1H, ddd, J=10.2, 2.5, 1.4 Hz), 6.79 (1H, d, J=12.9 Hz), 6.71 (1H, ddd, J=13.9, 8.8, 2.5 Hz), 6.49 (1H, t, J=2.3 Hz), 3.70-3.83 (4H, m), 3.19-3.32 (4H, m), 3.03-3.12 (4H, m), 2.92-3.03 (4H, m), 2.00 (3H, s). Mass Spectrum (ESI) m/e=441.2 (M+1).
