On December 1, 2001, Hirota, Kosaku; Kazaoka, Kazunori; Niimoto, Itaru; Sajiki, Hironao published an article.Safety of 2-Aminomalononitrile 4-methylbenzenesulfonate The title of the article was Novel and efficient synthesis of 8-oxoadenine derivatives. And the article contained the following:
A novel synthetic method for the preparation of 8-oxoadenine derivatives was reported. This widely applicable synthetic method was realized through the use of 5-amino-2,3-dihydro-2-oxo-1-(phenylmethyl)-1H-imidazole-4-carbonitrile as the key intermediates. A variety of substituents were successfully introduced to the 2- and 9-position of the 8-oxoadenine nucleus. The experimental process involved the reaction of 2-Aminomalononitrile 4-methylbenzenesulfonate(cas: 5098-14-6).Safety of 2-Aminomalononitrile 4-methylbenzenesulfonate
