In this paper, synthesis of 3-(2-bromo-4-methylbenzyl)-6-phenyl-1,2-dihydro-1,2,4,5-tetrazine acid hydrazide derivative say has been reported. The reaction was started by taking 2-bromobenzaldehyde as starting material. By using the many simple and common reaction, acid hydrazide derivative containing four nitrogen atoms have been completed. The structures of synthesized compounds are confirmed by their IR and 1H-NMR spectral data. Melting point of the compound has been determined by open capillary tube.
