Methanol → HCID 15721934, compound

Participants

Reaction Steps

Trimethyl orthoformate (31-8 g; 0.3 mol) was added dropwise to a slowly distilling solution of diaminomaleonitrile (32.4 g; 0.3 tool) in 1,4-dioxane (250 mL). The methanol that formed during the reaction was removed by distillation. The reaction mixture was concentrated in vacuo and cooled to room temperature. The precipitate was collected and crystallized from THF-pentane to yield 33.6 g (62%) of 2-amino-3-(methoxymethylenamino) maleonitrile having a melting point of 138°-139° C.
