使用Chemical intermediate.
製造方法Triethyl orthoformate (67.3 mg, 0.454 mol) and malononitrile (20.0 mg,0.302 mol) were andded to acetic anhydride (77.2 gm, 0.75 moles) and the mixture was refluxed for 4-5 h at 110-140°C. The reaction was monitored by GC. After the reaction is complete, it is cooled to room temperature. Concentrated the mixture at 70°C at reduced pressure to yield crude solid product and the pure product (Ethoxymethylenemalononitrile) was obtained through purified either by vacuum distillation.
