Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Methanone, (3-hydroxybenzo[b]thien-2-yl)phenyl- | HCID 4712192 | — |
| Reactant | Dimethylammonium acetate | HCID 57431419 | — |
| Product | (E)-2-[(Dimethylamino)phenylmethylene]-benzo[b]thiophen-3(2H)-one | HCID 70479181 | 18% |
Reaction Steps
Prepared as in Example 31 from 2-benzoyl-benzo[b]thiophen-3-ol and dimethylammonium acetate with a yield of 18% of theory; m.p. 179°-180° C. (ethyl acetate/petroleum ether 1:2). The product was identical to that prepared according to Example 4, based on its thin-layer chromatogram, elemental analysis and IR-spectrum.
