| 反応物 | Resorcinol | HCID 5054 | — |
| 反応物 | Diethyl 2-oxosuccinate,sodium salt | HCID 57351814 | — |
| 溶媒 | Phosphoric Acid | HCID 1004 | — |
| 生成物 | Ethyl 7-hydroxycoumarin-4-carboxylate | HCID 5702825 | 80% |
反応手順
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.
