反応手順
N-{5-[4-(trifluoromethyl)phenyl]thiophene-2-sulfonyl}pyrrole was prepared in the same manner as described in Example 32C using 4-trifluoromethylbenzene boronic acid and N-(5-bromothiophene sulfonyl)-pyrrole. Purification by column chromatography using 2% ethyl acetate/hexanes gave the pure sulfonamide as a white powder in 75% yield.
