実験手順

A mixture of 4-bromo-2,2-dimethyl-5-(pyridin-4-yl)furan-3(2H)-one (0.085 g, 0.32 mmol), 6-Fluoro-2-((4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy)methyl)quinoline (0.12 g, 0.32 mmol), and Cs2CO3 (0.52 g, 1.58 mmol) in toluene (5 mL) and water (2 mL) was degassed, added Pd(dppf)Cl2 (0.052 g, 0.06 mmol) under an inert atmosphere and degassed again. Then the reaction was refluxed for 2 h. The reaction mixture was filtered through a pad of Celite®, the filtrate was diluted with EtOAc (30 mL), washed with water (20 mL), brine (20 mL), dried over Na2SO4, filtered and concentrated in vacuo to obtain the crude product. The crude material was purified via silica gel column chromatography to afford 4-(4-((6-fluoroquinolin-2-yl)methoxy)phenyl)-2,2-dimethyl-5-(pyridin-4-yl)furan-3(2H)-one (35 mg, 25%) as a pale yellow solid. 1H NMR (500 MHz, d6-DMSO): δ 8.71 (d, J=8.5 Hz, 2 H), 8.42 (t, J=7.9 Hz, 1 H), 8.1 (t, J=8.4 Hz, 1 H), 7.70-7.61 (m, 3H), 7.44 (d, J=8.5 Hz, 2 H), 7.18 (d, J=7.4 Hz, 2 H), 7.11 (d, J=7.5 Hz, 2 H), 5.40 (s, 2 H), 1.44 (s, 6 H). MS: [M+H]: m/z=441.1. HPLC: 90.1% (RT-2.39 min), Column: Acquity BEH—C-18, 50×2.1 mm, 1.7 um. Mobile Phase: 0.025% TFA in Water (A), ACN (B), Flow rate: 0.5 ml/min (Gradient).
