✦ Synopsis
In the title compound, C 12 H 16 N 4 O 3 , all bond lengths and angles are within normal ranges. An O-HÁ Á ÁN and an N-HÁ Á ÁO intramolecular hydrogen bond contribute to the approximately planar molecular conformation. In the crystal structure, intermolecular N-HÁ Á ÁO and N-HÁ Á ÁN hydrogen bonds link the molecules into ribbons parallel to the [110] direction.
