Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | (5-Methylthiophen-2-yl)boronic acid | HCID 2734374 | — |
| Reactant | N-(5-bromothiophenesulfonyl)pyrrole | HCID 23445587 | — |
| Product | N-[5-(5-methyl-2-thienyl)thiophene-2-sulfonyl]pyrrole | HCID 22998476 | 72% |
Reaction Steps
N-[5-(5-methyl-2-thienyl)thiophene-2-sulfonyl]pyrrole was prepared in the same manner as described in Example 32C from 2-methylthiophene-5-boronic acid and N-(5-bromothiophene-2-sulfonyl)pyrrole. Purification by column chromatography using 2% ether/hexanes gave the pure sulfonamide in 72% yield as a white solid.
