Ethyl orthoformate → 4,5-Dicyanoimidazole
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Ethyl orthoformate | HCID 31214 | — |
| Reactant | Diaminomaleonitrile | HCID 2723951 | — |
| Product | 4,5-Dicyanoimidazole | HCID 70729 | — |
Reaction Steps
In another 5-step synthesis, diaminomaleonitrile can be reacted with triethyl orthoformate to give the imidazole-4,5-dinitrile which, after alkylation with dimethyl sulfate, hydrolysis and partial decarboxylation by heating in acetic anhydride, gives the compound of the formula Ia (R1 =CH3, X1 =COOH).
