실험 절차

To a solution of 75 mg (0.23 mmol) of N-(4-bromophenyl)-N-methyl-benzenesulfonamide in 4 mL of Et2O at −78° C. was added dropwise 285 μL (0.49 mmol) of a 1.7 M solution of tert-BuLi in pentane and the resultant mixture was stirred at −78° C. for 10 min. To this mixture was then added a solution of 81 mg (0.34 mmol) of N-ethoxyethyl-2-trifluoroacetylpyrrole in 3 mL THF and the mixture was allowed to gradually warm to room temperature over an 18 h period. The reaction mixture was quenched by the addition of a saturated aqueous solution of ammonium chloride and extracted with EtOAc. The combined organic layers were dried over Na2SO4, filtered and the filtrate was concentrated. The residue was purified by chromatography on silica gel (hexanes:EtOAc, 4:1) to give the title compound.
