Abstract: In the title compound, C16H21N3O3, the piperazine ring adopts a chair conformation, with its N-C bonds in pseudo-equatorial orientations. In the crystal, molecules are linked by O-HN hydrogen bonds, generating C(5) chains propagating in . Weak aromatic - stacking interactions also occur [centroid-centroid separation = 3.899 (1) Å].
