Abstract

A new synthetic method of 3-amino-5-substituted phenylamino-6-phenyl-1,2,4-triazines was reported. Benzoylthioformanilides were first condensed with aminoguanidine dihydrochloride in slightly acidic medium, then refluxed in alkaline medium (pH 8~9) to give title compounds by the elimination of hydrogen sulfide. Nine 1,2,4-triazines I (R = Ph, substituted Ph) were synthesized by this reaction in good yields.

Key words: AMINOGUANIDINE P, BENZAMINE P, BRONCHIECTASIS, BENZENE P, AMINOTRIAZINE P, TRIAZINE P, THIOFORMAMIDE
