In the title compound, C(11)H(18)N(4)O(2) (systematic name: 2-dimethyl-amino-5,6-dimethyl-pyrimidin-4-yl N,N-dimethyl-carb-amate), the pyrimidine ring and dimethyl-amino group are almost in the same plane, making a dihedral angle of 1.6 (1)°. The dihedral angle between the mean plane of the pyrimidine ring and that of the dimethyl-carbamate group is 83.42 (5)°. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds contribute to the stabilization of the packing.
