Hydrazidoyl halides in heterocyclic synthesis.II+: Synthesis of several new pyrazole, pyrazolo [5,1-c] 1,2,4-Triazine, pyrimidine and thiazole derivatives

ABSTRACT

Several new pyrazole, pyrazolo [5, 1-c]-1, 2, 4-triazine, pyrimidine and thiazole derivatives were synthesised by the reactions of 2-bromo-1-benzofurylglyoxal-2-[3-phenyl-pyrazol-5-yl]-hydrazone with a variety of reagents. Structures were established by elemental and spectral data
