실험 절차

To a solution of 1-(3-bromo-5-(4-chlorophenyl)-1,4-dimethyl-1H-pyrrol-2-yl)propan-1-one (compound 49b, 3.0 g, 8.81 mmol) in a mixture of toluene:ethanol (15 ml:45 ml) were added 4-aminosulfonylbenzene boronic acid (1.947 g, 9.69 mmol) and potassium carbonate (2.43 g, 17.61 mmol) at 25° C. in a sealed tube and a nitrogen gas was bubbled through it for 15 minutes. To the reaction mixture was the added tetrakis(triphenylphosphine)palladium(0) (0.51 g, 0.44 mmol) under nitrogen atmosphere and reaction mixture was heated at about 90 to about 95° C. for 18 hr under stirring. The progress of the reaction was monitored by TLC. The reaction mixture was then cooled to 25° C. and filtered through celite. The celite cake was washed with 10% methanol in dichloromethane. The combined filtrate so obtained was concentrated under reduced pressure to obtain a crude product, which was then purified by flash column chromatography using 40% ethyl acetate in hexanes as an eluent to obtain the title compound (1.22 g, 33.2%).
