The title mol-ecule, C(18)H(18)N(2)O(2), is V-shaped with the pyrazoline moiety being inclined to the adjacent phenyl ring by an angle of 6.49 (9)°, while the 4-meth-oxy-substituted ring is inclined to the pyrazoline ring by 82.99 (9)°. In the crystal, adjacent mol-ecules are linked by C-H⋯O inter-actions, forming chains propagating in [100]. There are also C-H⋯π inter-actions involving adjacen...

The asymmetric unit of the title compound, C18H18ClN3OS·C2H5OH, comprises a pyrazoline derivative and an ethanol solvent mol-ecule. In the mol-ecule of the pyrazoline derivative, the pyrazole ring adopts an envelope conformation with the C atom bearing the eth-oxy-phenyl substituent as the flap. The dihedral angle between the benzene rings is 74.22 (7)°. The eth-oxy group is coplanar with the a...

A new series of 2-(ortho & para substituted phenoxy)1-(3-(3-chloro-4-methoxyphenyl)-5-(substituted phenyl)-4,5dihydropyrazol-1-yl)ethanone were synthesized. Ortho and para substituted phenol was refluxed with ethylchloroacetate in dry acetone in presence of anhydrous potassium carbonate to yield ethyl (ortho & para substituted phenoxy) acetate (1). The substituted ester on reaction with hydrazi...
