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).
