Reaction Steps
To a solution of 4′-[(5-bromo-2-butyl-4-methyl-6-oxopyrimidin-1(6H)-yl)methyl]biphenyl-2-carbonitrile (0.5 g), tributyl(2-thienyl)tin (0.64 g) and lithium chloride (0.15 g) in N,N-dimethylformamide (10 mL) was added dichlorobis(triphenylphosphine)palladium (0.04 g), and the mixture was stirred for 12 hr under an argon atmosphere. The reaction mixture was allowed to cool to room temperature and diluted with ethyl acetate. A 20% aqueous potassium fluoride solution was added, and the mixture was stirred for 2 hr. The insoluble material was filtered off through celite. The organic layer of the filtrate was separated, washed 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. The residue was purified by silica gel column chromatography to give the title compound (0.38 g, 75%) as a colorless viscous oil.
