Taylor, Edward C. published the artcilePteridines. 49. Synthesis of 2,4-diamino-6,8-dihydro-7-aryl-8-oxopyrrolo[3,4-g]pteridines, Application In Synthesis of 5098-14-6, the publication is Journal of Organic Chemistry (1982), 47(1), 116-19, database is CAplus.
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).
