Dimerizing condensation of alkylidenepropanedinitriles and alkylidenecyanamides. - A general approach to aniline, aminopyridine, and aminopyridine derivatives

Hartke,Sauerbier,Richter

, p. 279 - 284 (1992)

The base catalyzed dimerizing condensation of (α-methylthioalkylidene)propanedinitriles (e.g. 8) yields 2-aminobenzene-1,3-dicarbonitriles (e.g. 13), of (α-methylthioalkylidene)cyanamides (e.g. 14) 2-aminopyrimidines (e.g. 16, 37). The mixed condensation
