The title compound, C(26)H(25)Cl(3)N(6)O(4), was prepared by the reaction of (Z)-ethyl 3-amino-3-(4-chloro-phen-yl)-2-cyano-acrylate and 4-chloro-3-ethyl-1-methyl-1H-pyrazole-5-carbonyl chloride. The dihedral angles between the chloro-benzene and the two pyrazole rings are 59.8 (2) and 33.3 (2)°. The two pyrazole rings are oriented to each other at a(More)
The title compound, C(19)H(14)ClFN(2)O(3), was prepared by the reaction of ethyl (Z)-3-amino-2-cyano-3-(4-fluoro-phen-yl)acrylate and 4-chloro-benzoyl chloride. The dihedral angle between the chloro-benzene and fluoro-benzene rings is 66.18 (19)°. In addition to an intra-molecular N-H⋯O hydrogen bond, there are inter-molecular C-H⋯O and C-H⋯N hydrogen(More)
