Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Boronic acid, (4-ethylphenyl)- | HCID 2734352 | — |
| Reactant | N-(5-bromothiophenesulfonyl)pyrrole | HCID 23445587 | — |
| Product | N-[5-(4-ethylphenyl)thiophene-2-sulfonyl]pyrrole | HCID 23445382 | 81% |
Reaction Steps
N-[5-(4-Ethylphenyl)thiophene-2-sulfonyl]pyrrole was prepared, in the same manner as described in Example 13C, from 4-ethylphenylboronic acid and N-(5-bromothiophenesulfonyl)pyrrole. Purification by column chromatography using 10% ethyl acetate/hexanes gave the pure sulfonamide as a tan solid in 81% yield.
