Reaction Steps

tert-butyl ({5-bromo-1-[(3-methoxyphenyl)sulfonyl]-1H-pyrrol-3-yl}methyl)methylcarbamate (459 mg), (2-fluoropyridin-3-yl)boronic acid (169 mg), sodium carbonate (254 mg), and tetrakis(triphenylphosphine)palladium (173 mg) were suspended in 1,2-dimethoxyethane (10 mL) and water (4 mL), and the mixture was stirred at 105° C. for 2 hr. The reaction mixture was cooled 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 silica gel column chromatography (eluent: hexane-ethyl acetate=4:1→2:1) to give the title compound as a pale-yellow oil (yield 303 mg, 64%).
