Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Aniline | HCID 6115 | — |
| Reactant | Diethyl (ethoxymethylene)malonate | HCID 6871 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | 2-Phenylaminomethylene-malonic acid diethyl ester | HCID 264327 | — |
Reaction Steps
Freshly distilled aniline (46.5 g) and diethyl ethoxymethylene malonate (108 g) were heated together on a steam bath for two hours. The ethanol formed in the reaction was then evaporated off under vacuum to give the intermediate diethyl (anilinomethylene)malonate, m.p. 48° C.
