実験手順

(1H-Benzo[d]imidazol-2-yl)(4-(3-chloropyrazin-2-yloxy)phenyl)methanone (1.0 g, 2.8 mmol), potassium acetate (2.1 g, 21.0 mmol), 2-(4-methoxy-1-cyclohexen-1-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (0.88 g, 3.7 mmol), and bis[di-tert-butyl(phenyl) phosphane]dichloropalladium (0.13 g, 0.213 mmol) were taken up in 40 mL of 3:1 MeCN:water. The mixture was purged with nitrogen and heated to 100° C. After 12 hours, the mixture was cooled to room temperature and diluted with 40 mL of water. The mixture was extracted twice with 30 mL of 9:1 chloroform:IPA. The combined organic extracts were dried over MgSO4. Filtration and concentration under reduced pressure, followed by flash chromatography on silica gel (0.5 to 5% MeOH/DCM) afforded 1H-Benzimidazol-2-yl(4-((3-(4-methoxy-1-cyclohexen-1-yl)-2-pyrazinyl)oxy)phenyl)methanone as a yellow solid. MS (ESI, pos. ion) m/z: 427.1 (M+1). IC50 (uM) +++++.
