Abstract
In the present investigation, a series of 4-(4-(dimethylamino) benzyl)-3-methyl-1H
pyrazol-5(4H)-one analogues of pyrazole were synthesized by cyclization of mannich base with
hydrazine hydrate. The nitrogen functionality of 4-(4-(dimethylamino) benzyl)-3-methyl-1H
pyrazol-5(4H)-one was alkylated with different halogenated alkylated substituted chain in the
presence of base. The chemical structure of compounds were proved by IR, MASS, 1HNMR
spectroscopy data and elemental analysis. The antitubercular activity of these compounds were
evaluated by microdilution method against M. Tuberculosis H37Rv micobactrium strain of M.
Tuberculosis compared with standard INH, RIF & ETM.
