The asymmetric unit of the title Schiff base compound, C(12)H(15)N(3)O, contains two crystallographically independent mol-ecules, with both existing in an E configuration with respect to the C=N double bonds. In the crystal structure, inter-molecular N-H⋯N and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.
