On June 16, 1997, Peinador, Carlos; Quintela, Jose Ma.; Moreira, Maria J. published an article.Reference of 2-Aminomalononitrile 4-methylbenzenesulfonate The title of the article was A short and facile synthesis for heteromine A. And the article contained the following:
The first and efficient synthesis of the new purinium natural product, heteromine A, involving 5-amino-4-cyano-1-methylimidazole and N,N-dimethyldichlomethyleniminium chloride was reported. The experimental process involved the reaction of 2-Aminomalononitrile 4-methylbenzenesulfonate(cas: 5098-14-6).Reference of 2-Aminomalononitrile 4-methylbenzenesulfonate
