A method for producing N-(2-amino-1,2-dicyanovinyl)imidates represented by the following formula (1-III) under low temperature conditions within a short period of time in high yield is provided. In addition, a method for producing N-(2-amino-1,2-dicyanovinyl)formamidine represented by the following formula (2-II) which is suitably applicable to a cyclization reaction for producing AICN, AICA or the like and which enhances yield of the cyclization reaction is provided. In addition, a method for producing aminoimidazole derivatives represented by the following formula (3-V) in high yield by using diaminomaleonitrile as a starting material is provided.
