Abstract
Abstract 1,3-Diemthyl(5H,7H)imidazo(4,5- d pyrimidine-2,4,6-trithione ( 1 ) was synthesized by the reaction of carbon disulfide with 1,3-dimethyl-4-cyano-5-aminoimidazolidine-2-thione ( 3 ) which was produced by reacting trimethylsilyl cyanide with methyl isothiocyanate followed by methanolysis. An unusual reversible formation of the dimethylamine salt of 1 is also described.
