実験手順

A mixture of N-[3-(5-bromo-1H-benzimidazol-1-yl)phenyl]-N′-(2,2,2-trifluoro ethyl)urea (250.0 mg, 0.6050 mmol), [3-(methoxycarbonyl)phenyl]boronic acid (160 mg, 0.91 mmol Aldrich, Cat. No. 591130), tetrakis(triphenylphosphine)palladium(0) (40 mg, 0.04 mmol Aldrich, Cat. No. 216666) and sodium carbonate (130 mg, 1.2 mmol) in 1,4-dioxane (10 mL) and a few drops of water was heated at 120° C. overnight under nitrogen. After the reaction was cooled to r.t., 1.0 M sodium hydroxide in water (2.4 mL,) was added to the above mixture. The reaction mixture was heated at 100° C. 2 h., and then cooled to r.t. The reaction mixture was diluted with ethyl acetate, and extracted with 1N NaOH aqueous solution twice. The combined aqueous phases were acidified to pH˜2 with 6 M HCl aqueous solution, and then extracted with ethyl acetate twice. The combined organic phases (only the extracted portion with acidic aqueous solution) were washed with brine, and dried over MgSO4. After filtration, the filtrate was concentrated under reduced pressure to afford the desired product. LCMS (M+H)+: m/z=455.1.
