(Z)-4-[(Ethyl-amino)(furan-2-yl)methyl-idene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one.

ABSTRACT: In the crystal of the title compound, C(17)H(17)N(3)O(2), the mol-ecules exist in the keto-enamine form. The pyrazole ring is oriented at 10.59?(4) and 57.98?(5)° to the phenyl and furyl rings, respectively, and the dihedral angle between phenyl and furyl rings is 73.30?(11)°. An intra-molecular N-H?O hydrogen bond occurs between imino and carbonyl groups. In the crystal, weak C-H?O hydrogen bonds link the mol-ecules into supra-molecular chains along the b axis.
