In this work, we described an easy preparation of substituted 4-amino-5-cyano-1,3-thiazoles. These compounds have been used as starting materials to obtain two classes of compounds. New substituted [1,3]thiazolo[4,5-e]pyridines were synthesized in one step via Friedl?nder reaction. Diazotation of 4-amino-5-cyano-1,3-thiazoles afforded 4-chloro[1,3]thiazolo[4,5-d][1,2,3]triazines in one step. The later was substituted by a secondary amine to obtain substituted 4-amino[1,3]thiazolo[4,5-d][1,2,3]triazines.

4-Aminothiazolin-2-one-hydrazones 3 are obtained by succesive treatment of the title compound 1 with dimethyl sulfate and hydrazinehydrate.The rearrangement of 4-aminothiazolin-2-ylidenmalononitrile 7 derived from 1 yields the 2,4-diamino-thiophene deriva
