Yong-Jun Shen, and Mei Xu, and Chong-Guang Fan

In the title compound, C(6)H(7)ClN(2)O, the mol-ecules are situated on mirror planes, so H atoms of two methyl groups were treated as rotationally disordered over two orientations each. The crystal packing exhibits weak inter-molecular C-H⋯O inter-actions and short Cl⋯N contacts of 3.046 (2) Å.
