چکیده
In the title compound, C(24)H(20)BrN(3)O(4)S, the central benzene ring makes dihedral angles of 17.13 (13), 39.83 (13) and 58.37 (13)°, respectively, with the pyrazolone ring, the bromo-benzene ring and the terminal phenyl ring. In the crystal structure, the packing is stabilized by a weak non-classical inter-molecular C-H⋯O hydrogen bond which links the mol-ecules into a chain propagating in [100].

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...

In the title compound, C19H17Cl2N3O2, the amide group is planar and, through N-H⋯O hydrogen bonding to an adjoining mol-ecule, forms dimers of the R2(2)(10) type. As a result of steric repulsion, the amide group is rotated with respect to both the dichloro-phenyl and 2,3-dihydro-1H-pyrazol-4-yl rings, making dihedral angles of 71.63 (11) and 57.93 (10)°, respectively. The dihedral angle between...
