Abstract

5-Benzylidene-3-(p-chlorophenyl)-2-aminothiocarbonyl-1,2,4-triazine (2) was prepared via condensation of oxazolinone (1) with thiosemicarbazide. Fused 1,2,4-triazine derivatives (3, 4 and 9) were synthesized from the reaction of compound 2 with ω-bromomethyl aryl ketones, ethyl chloroacetate, and acetic anhydride. Treatment of 4 with acetic anhydride and aromatic aldehydes yielded the corresponding acetyl, diacetyl derivatives (6 and 7) and 7-benzylidene-5-(p-chlorophenyl)-4-thioxo-3-arylidene-1,2,4-triazino [2,1-a]-1,2,4-triazine-1,8-diones (8). The electron impact mass spectra of both the above series of compounds have also been recorded and their fragmentation pattern is discussed. All synthesized fused 1,2,4-triazine derivatives were primary in vitro screened for their antimicrobial and antitumor activity.
