Abstract

The title compound, C(12)H(16)N(2)O(2), crystallized from toluene with two independent mol-ecules in the asymmetric unit. The dihedral angles between the amide groups and the benzene ring are 60.87 (11) and 54.08 (11)° in one independent molecule and 60.13 (11) and 64.64 (11) in the other. The crystal structure features weak C-H⋯O hydrogen bonds and C-H⋯π inter-actions.
