Gompper, Rudolf published the artcileAminopyridines, aminopyrimidines, and tris(dimethylamino) benzene from (aza) vinamidinium and (aza)pentamethinium salts, Application of N,N-Dimethylpyrimidin-4-amine, the publication is Angewandte Chemie (1981), 93(3), 298-9, database is CAplus.
Reaction of H2XC(NMe2):N+:CRNMe2.ClO4– (X = CH, R = H, Ph, Me, NMe2; X = N, R = H) with Me2NCH(OEt)2 gave 74-90% Me2NCH:XC(NMe2):N+:CRNMe2.ClO4– (I). I (X = CH) were cyclized with NH4OAc to give the pyrimidines II (R = H, Ph, NMe2). The pyridine III was obtained by treating I (X = CH, R = Me) with base. 1,3,5-(Me2N)3C6H3 was obtained in 70% yield by treating Me2NCMe:C:C(NMe2)2.HClO4 with Me2NCMe(OEt)2.
