Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 4-Isopropylphenylboronic acid | HCID 2773480 | — |
| Reactant | N-(5-bromothiophenesulfonyl)pyrrole | HCID 23445587 | — |
| Product | N-[5-(4-isopropylphenyl)thiophene-2-sulfonyl]pyrrole | HCID 22998466 | 84% |
Reaction Steps
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.
