Reaction Conditions

Reaction Steps

A mixture of tert-butyl {[5-bromo-1-(pyridin-3-ylsulfonyl)-1H-pyrrol-3-yl]methyl}methylcarbamate (430 mg), 4-(methanesulfonyl)phenylboronic acid (300 mg), tetrakis(triphenylphosphine)palladium (115 mg), sodium carbonate (320 mg), 1,2-dimethoxyethane (10 mL) and water (10 mL) was stirred under a nitrogen atmosphere at 80° C. for 14 hr. The reaction mixture was allowed to cool to room temperature, filtered through celite, and the filtrate was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane-ethyl acetate=2:1→1:2) to give the title compound as an oil (yield 275 mg, 64%).
