실험 절차

N-{[3-(3,4-methylenedioxy)phenyl]thiophene-2-sulfonyl}pyrrole was prepared in the same manner as described in Example 32C using 3,4-methylenedioxyphenylboronic acid and N-(3-bromothiophene-2-sulfonyl)pyrrole. The crude product was purified by flash column chromatography on silica gel using 2% EtOAc in hexane as the eluent resulting in N-{[3-(3,4-methylenedioxy)phenyl]thiophene-2-sulfonyl}pyrrole in a 90% yield.
