Ethyl 4-amino-5-cyano-6-[(2-hydroxyethyl)amino]-2-methylnicotinate.

In the title compound, C12H16N4O3, all bond lengths and angles are within normal ranges. An O—H...N and an N—H...O intramolecular hydrogen bond contribute to the approximately planar molecular conformation. In the crystal structure, intermolecular N—H...O and N—H...N hydrogen bonds link the molecules into ribbons parallel to the [1 0] direction. [ABSTRACT FROM AUTHOR]
