Versuchsvorschrift

To a solution of 4′-[(5-bromo-2-butyl-4-cyclopropyl-6-oxopyrimidin-1(6H)-yl)methyl]biphenyl-2-carbonitrile (0.5 g) and 2-methyl-2,3-dihydro-1-benzofuran-5-ylboronic acid (0.29 g) in 1,4-dioxane (10 mL) were added 2 M aqueous cesium carbonate solution (2 mL) and [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium (0.05 g), and the mixture was stirred at 90° C. for 12 hr under an argon atmosphere. The reaction mixture was diluted with ethyl acetate, and the insoluble material was filtered off through celite. The filtrate was washed successively with 1 M hydrochloric acid, saturated aqueous sodium hydrogen carbonate and saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography to give the title compound (0.47 g, 84%) as a pale-yellow solid.
