Reaction Steps

A suspension of tert-butyl {[5-bromo-1-(pyridin-3-ylsulfonyl)-1H-pyrrol-3-yl]methyl}methylcarbamate (430 mg), (2-fluoropyridin-3-yl)boronic acid (221 mg), sodium carbonate (254 mg) and tetrakis(triphenylphosphine)palladium (173 mg) in 1,2-dimethoxyethane (10 mL) and water (5 mL) was stirred at 105° C. for 1 hr. The reaction mixture was cooled to room temperature. Water was added to the reaction mixture 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=6:1→1:1) to give the title compound as a pale-yellow oil (yield 310 mg, 69%).
