実験手順
N-[5-(4-propylphenyl)thiophene-2-sulfonyl]pyrrole was prepared in the same manner as described in Example 33C, from 4-propylphenyl boronic acid and N-(5-bromothiophenesulfonyl)pyrrole. Purification by column chromatography using 10% ethyl acetate/hexanes gave the pure sulfonamide as a white solid in 55% yield, m.p. 106°-108° C.
