Sym-triazines have been documented for their antitumor, antimicrobial and anti-cancer action. The present work aims to derive a variety of 1,3,5-triaryl-1,3,5-hexahydro-s- triazines from the reaction of aryl-amines with aqueous formaldehyde. The preparation of the derivatives has been achieved according to the following steps: 1) The synthesis of the hexahydro-1,3,5-s-triazine (Ha), 2) The base catalyzed condensation of hexahydro-1,3,5-s-triazine (Ha), 3) The second hexahydro-1,3,5-s-triazine (Hb) is treated with hydrazine hydrate, 4) The reaction of carbohydrazide (Hb1) with formic acid, 5)...
