실험 절차

Under an argon atmosphere, a mixture of 1-[(6-chloropyridin-3-yl)sulfonyl]-5-(2-fluorophenyl)-1H-pyrrole-3-carbaldehyde (365 mg), methylboronic acid (90 mg), tetrakis(triphenylphosphine)palladium (116 mg), potassium carbonate (691 mg) and 1,4-dioxane (25 mL) was stirred at 80° C. for 3 days. The reaction mixture was poured into saturated aqueous sodium hydrogencarbonate solution, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane-ethyl acetate=19:1→1:1) to give the title compound as a yellow solid (yield 134 mg, 39%).
