참여 물질
| 역할 | 이름 | HCID | 투입량 |
|---|---|---|---|
| 반응물 | 1-(Thiophen-3-yl)ethanone | HCID 15116 | — |
| 반응물 | Dimethylformamide dimethyl acetal | HCID 78373 | — |
| 생성물 | 3-Dimethylamino-1-thien-3-ylpropen-1-one | HCID 596466 | 87% |
반응 단계
A mixture of 48.4 g of 3-acetylthiophene and 75 ml of dimethylformamide dimethyl acetal, under nitrogen, is heated for 15 hours on a steam bath. The reaction is concentrated in vacuo and the residue crystallized from methylene chloride/hexane to give 60.55 g (87%) of the desired product, mp 89°-90° C.
