実験手順

To a stirred solution of 5′-bromo-1′-(7-fluoro-3-methyl-2-(2-pyridinyl)-4-quinolinyl)-6′-(4-morpholinyl)-1′,2,2′,3,5,6-hexahydrospiro[pyran-4,3′-pyrrolo[3,2-b]pyridine] (140 mg, 0.237 mmol) in 1,4-dioxane (4 mL) was added bis(tri-tert-butylphosphine)palladium (0) (12.12 mg, 0.024 mmol), cesium fluoride (36 mg, 0.237 mmol) and tri-n-butyl(vinyl)tin (90 μL, 0.285 mmol) and the reaction was heated at 120° C. for 3 h in the microwave. After this time the reaction was partitioned between EtOAc (50 mL) and water (15 mL). The separated organic layer was dried over MgSO4, filtered and evaporated in vacuo. The crude reaction was purified by column chromatography on silica gel (DCM to DCM:MeOH:—NH4OH (9:1:0.4), 1:0 to 2:1 as eluent) to give 5′-ethenyl-1′-(7-fluoro-3-methyl-2-(2-pyridinyl)-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 8.66-8.80 (1H, m), 7.85-7.96 (3H, m), 7.73 (1H, dd, J=9.3, 6.0 Hz), 7.42 (1H, ddd, J=6.8, 4.8, 2.1 Hz), 7.23-7.30 (1H, m), 7.09 (1H, dd, J=17.2, 10.8 Hz), 6.30 (1H, dd, J=17.3, 2.6 Hz), 5.96 (1H, s), 5.18-5.36 (1H, m), 4.23-4.32 (2H, m), 3.93-4.03 (2H, m), 3.77 (4H, t, J=4.6 Hz), 3.61-3.69 (2H, m), 2.68-2.80 (4H, m), 2.27-2.47 (5H, m), 1.77-1.90 (2H, m). Mass Spectrum (ESI) m/e=538.2 (M+1).
