On January 1, 1982, Taylor, Edward C.; Dumas, Donald J. published an article.Related Products of 5098-14-6 The title of the article was Pteridines. 49. Synthesis of 2,4-diamino-6,8-dihydro-7-aryl-8-oxopyrrolo[3,4-g]pteridines. And the article contained the following:
Reaction of Et 4-chloro-2-oximino-3-oxobutyrate with aminomalononitrile tosylate followed by deoxygenation of the resulting pyrazine 1-oxide provides the cyanopyrazine (I). Treatment of I with arylamines gives the (arylaminomethyl)cyanopyrazines II (R = H, Me) which are readily cyclized to the oxopyrrolopyrazines III. Condensation of III with guanidine acetate in DMF then provides the title compounds IV (R = H, Me). The experimental process involved the reaction of 2-Aminomalononitrile 4-methylbenzenesulfonate(cas: 5098-14-6).Related Products of 5098-14-6
