(Z)-4-[(Ethyl­amino)(furan-2-yl)methyl­idene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one

In the crystal of the title compound, C(17)H(17)N(3)O(2), the mol­ecules 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 intra­molecular N—H...

description In the crystal of the title compound, C(17)H(17)N(3)O(2), the mol­ecules 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 intra­molecular N—H⋯O hydrogen bond occurs between imino and carbonyl groups. In the crystal, weak C—H⋯O hydrogen bonds link the mol­ecules into supra­molecular chains along the b axis.
