Reaction Steps

1′-(5,7-difluoro-3-methyl-2-(piperazin-1-yl)quinolin-4-yl)-6′-morpholino-1′,2,2′,3,5,6-hexahydrospiro[pyran-4,3′-pyrrolo[3,2-b]pyridine] (50 mg, 0.093 mmol) in DCM (5.0 mL) was treated with triethylamine (0.019 mL, 0.140 mmol) and methanesulfonyl chloride (7.3 μL, 0.093 mmol) and the reaction was stirred at rt overnight. After this time the reaction was partitioned between EtOAc and water. The separated organic layer was dried over MgSO4 and evaporated in vacuo. Purification by reverse-phase HPLC (10% to 95% acetonitrile in water) gave 1′-(5,7-difluoro-3-methyl-2-(4-(methylsulfonyl)piperazin-1-yl)quinolin-4-yl)-6′-morpholino-1′,2,2′,3,5,6-hexahydrospiro[pyran-4,3′-pyrrolo[3,2-b]pyridine]. 1H NMR (400 MHz, chloroform-d) δ ppm 7.57 (1H, d, J=2.3 Hz), 7.37 (1H, dt, J=9.8, 1.3 Hz), 6.78 (1H, ddd, J=11.8, 9.0, 2.4 Hz), 5.65 (1H, d, J=2.3 Hz), 4.04-4.25 (2H, m), 3.83-3.97 (2H, m), 3.69-3.78 (4H, m), 3.30-3.65 (10H, m), 2.90-3.09 (4H, m), 2.86 (3H, s), 2.26-2.39 (2H, m), 2.25 (3H, s), 1.78 (1H, d, J=13.3 Hz), 1.64-1.75 (1H, m).
