Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 4-(Trifluoromethyl)phenylboronic acid | HCID 2734389 | — |
| Reactant | N-(5-bromothiophenesulfonyl)pyrrole | HCID 23445587 | — |
| Product | N-{5-[4-(trifluoromethyl)phenyl]thiophene-2-sulfonyl}pyrrole | HCID 22998451 | 75% |
Reaction Steps
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.
