Freeman, Fillmore published the artcileReaction of aminopropanedinitrile 4-methylbenzenesulfonate (aminomalononitrile p-toluenesulfonate (tosylate)) with isothiocyanates, Computed Properties of 5098-14-6, the publication is Journal of Organic Chemistry (1991), 56(15), 4645-8, database is CAplus.
Aminopropanedinitrile tosylate reacts with isothiocyanates RNCS (R = Bu, 4-MeOC6H4, Ph, 4-ClC6H4, 4-O2NC6H4, 1-naphthyl) in 1-methyl-2-pyrrolidinone to give 2,5-diaminothiazole-4-carbonitriles I. I (R = 4-MeOC6H4, Ph) react with H2NCH:NH.AcOH to give thiazolopyrimidines II (R1 = H). I (R = Ph) also reacts with MeC(OEt)3 to give II (R = Ph, R1 = Me).
