4-Aminoantipyrine was utilized as key intermediate for the synthesis of pyrazolone derivatives bearing biologically active moieties. The newly synthesized compounds were characterized by IR, 1H- and 13C-NMR spectral and microanalytical studies. The compounds were screened as anticancer agents against a human tumor breast cancer cell line MCF7, and the results showed that (Z)-4-((3-amino-5-imino...

Mol-ecules of the the title compound, C(21)H(24)Cl(2)N(2)O(2), are located on a twofold rotation axis, which passes through the C atom linking the two N atoms. Two intra-molecular O-H⋯N hydrogen bonds were observed. In the crystal, non-classical inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains along the a axis. The crystal studied was a racemic twin.
