Coupling the diazonium salts of 2-aminobenzothiazoles with malononitrile gave 2-(benzothiazoly-hydrazono)- malononitriles which then reaced with hydrazine hydrate, phenylhydrazine and guanidine nitrate to form 4'- (benzothiazolyl-2-azo)-3', 5'-diaminopyrazoles, 4'- (benzothiazolyl-2-azo)-3', 5'-diamino-2'-phenylpyrazoles and 5'-(benzothiazoly-2-azo)-2', 4' 6'-triaminopyrimidines respectively.
