An efficient procedure for the synthesis of substituted pyrazoles was developed. Claisen-Schmidt condensation of 2,4,5-trimethoxybenzaldehyde and substituted acetophenone in the presence of aqueous potassium hydroxide produced chalcones. An acid catalyzed cyclocondensation reaction of chalcones with 3-chlorophenylhydrazine hydrochloride produced substituted pyrazolines in good yields. The synthesized new compounds were characterized by spectral studies and elemental analysis; and some of the intermediate chalcones by single crystal X-ray diffraction studies and evaluated in vitro for their antimicrobial susceptibilities.
