PROCEDURE

实验过程

To a solution of 4-bromo-2-fluoro-1-iodobenzene (380 mg, 1.3 mmol) in THF (10 mL) was added tert-butyl[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazol-1-yl]acetate (390 mg, 1.3 mmol), 2M sodium carbonate in water (2.5 mL) and tetrakis(triphenylphosphine)palladium (40 mg, 0.04 mmol). The solution was degassed with N2, and heated at 80° C. overnight. The mixture was cooled to RT, poured into water, extracted with EtOAc, washed with brine, dried over MgSO4, filtered, and concentrated. The residue was purified by flash chromatograph on a silica gel column with EtOAc in Hexanes (30%) to afford the desired compound. LCMS: (M+57)=299.0.
