Reaction Steps
tert-Butyl ({4-bromo-5-[(3-methoxyphenyl)thio]-2-thienyl}methyl)methylcarbamate (596 mg), (2-fluorophenyl)boronic acid (225 mg), sodium carbonate (341 mg) and tetrakis(triphenylphosphine)palladium (0) (155 mg) were suspended in a mixture of 1,2-dimethoxyethane (10 mL) and water (4 mL), and the suspension was stirred at 105° C. for 4 hr under a nitrogen atmosphere. The reaction mixture was allowed to cool to room temperature, water was added, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by basic silica gel column chromatography (eluent: hexane-ethyl acetate=19:1→9:1) to give the title compound as a colorless oil (yield 459 mg, yield 75%).
