description

The title compound, C8H11N3O3, crystallizes with Z' = 4. One pyrazole N atom is substituted and excluded from inter­molecular contacts. The amine N, acetyl O and an ester O atom are involved in the formation of nearly planar mol­ecular layers. The layers are perpendicular to the c axis, with an inter­layer distance of 3.333 Å. The hydrogen-bonding patterns are similar for each mol­ecule, i.e. intra­molecular N-H...O, as well as inter­molecular N-H...O and C-H...N(pyrazole), bonds are present.
