2-氨基苯并噻唑重氮盐与丙二腈偶联, 生成2-(苯并噻唑腙基)-丙二腈, 然后分别与水合肼, 苯肼和硝酸胍反应, 形成相应的4'-(苯并噻唑-2-偶氮)-3',5'-二氨基吡唑, 4'-(苯并噻唑-2-偶氮)-3',5'-二氨基-2'-苯并吡唑和5'-(苯并噻唑-2-偶氮)-2',4',6'-三氨基嘧啶.

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.
