Versuchsvorschrift

Tert-Butyl 4-(5,7-difluoro-3-methyl-4-(6′-(4-morpholinyl)-2,3,5,6-tetrahydrospiro[pyran-4,3′-pyrrolo[3,2-b]pyridin]-1′(2′H)-yl)-2-quinolinyl)-1-piperazinecarboxylate (450 mg, 0.70 mmol) was dissolved in DCM (5.0 mL) and cooled to 0° C. TFA (5.0 mL, 65.0 mmol) was then added and the reaction mixture was allowed to warm to rt and stirred for 2.5 h. The reaction was diluted with DCM and concentrated to dryness. The residue was then converted to the free amine by eluting through an SCX column with 0 to 2M ammonia in MeOH to give 1′-(5,7-difluoro-3-methyl-2-(1-piperazinyl)-4-quinolinyl)-6′-(4-morpholinyl)-1′,2,2′,3,5,6-hexahydrospiro[pyran-4,3′-pyrrolo[3,2-b]pyridine]. 1H NMR (400 MHz, chloroform-d) δ ppm 7.56 (1H, d, J=2.3 Hz), 7.36 (1H, ddd, J=9.9, 2.5, 1.3 Hz), 6.73 (1H, ddd, J=11.8, 9.1, 2.5 Hz), 5.66 (1H, d, J=2.3 Hz), 4.04-4.21 (2H, m), 3.80-3.97 (2H, m), 3.70-3.79 (4H, m), 3.56 (2H, qd, J=11.6, 2.4 Hz), 3.27-3.46 (4H, m), 3.02-3.18 (4H, m), 2.90-3.02 (4H, m), 2.26-2.38 (2H, m), 2.24 (3H, s), 1.97 (1H, br. s.), 1.79 (1H, d, J=13.3 Hz), 1.70 (1H, dd, J=13.6, 1.9 Hz). Mass Spectrum (ESI) m/e=537.3 (M+1).
