참여 물질
| 역할 | 이름 | HCID | 투입량 |
|---|---|---|---|
| 반응물 | Resorcinol | HCID 5054 | — |
| 반응물 | Diethyl 2-oxosuccinate,sodium salt | HCID 57351814 | — |
| 용매 | Phosphoric Acid | HCID 1004 | — |
| 생성물 | Ethyl 7-hydroxycoumarin-4-carboxylate | HCID 5702825 | 80% |
반응 단계
0.10 mole resorcinol and 0.12 mole sodium diethyl oxalacetate is heated to 80° C. for 1 hour in 60 ml concentrated phosphoric acid. 4-Carbethoxy-7-hydroxy-coumarin is thus obtained at an 80% yield in the form of a viscous oil.
