実験手順
N-[5-(4-isopropylphenyl)thiophene-2-sulfonyl]pyrrole was prepared in the same manner as described in Example 33C, from 4-isopropylphenyl boronic acid and N-(5-bromothiophene sulfonyl)-pyrrole. Purification by column chromatography using 10% ethyl acetate/hexanes gave the pure sulfonamide as an off white colored solid in 84% yield, m.p. 112°-114° C.
