Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Urea | HCID 1176 | — |
| Reactant | Methanone, (3-hydroxybenzo[b]thien-2-yl)phenyl- | HCID 4712192 | — |
| Product | HCID 178510717 | HCID 178510717 | 55% |
Reaction Steps
Prepared as in Example 41 from 2-benzoyl-benzo[b]thiophen-3-ol, but using urea instead of ammonium acetate, with a yield of 55% of theory; m.p. 121°-122° C. (petroleum ether/ethyl acetate 2:1). The product was identical to that of Example 1, based on its TLC, mixed melting point and IR-spectrum.
