(Z)-4-{1-[(2-Hy-droxy-ethyl)-amino]-ethyl-idene}-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one.

ABSTRACT: In the title compound C(14)H(17)N(3)O(2), the dihedral angle between the rings is 16.68?(13)°. Although the compound crystallizes in the keto form, the possibility of keto-enamine-enol-imine tautomerism is explained by a strong intra-molecular N-H?O hydrogen bond.
