The title compound, C(19)H(23)N(3)O(2), was prepared by condensing 4-diethyl-amino-2-hy-droxy-benzaldehyde and 4-methyl-benzo-hydrazide in methanol. The asymmetric unit contains two independent mol-ecules in which the two benzene rings make dihedral angles of 30.3 (3) and 18.9 (3)°. Intra-molecular O-H⋯N hydrogen bonds are observed in both mol-ecules. The crystal structure is stabilized by N-H⋯O hydrogen bonds, which form chains along the a axis.
