3-(4-Methylpiperazin-1-yl) isobenzofuran-1(3H)-one

Abstract

In the molecule of the title compound, C13H16N2O2, the phthalide ring system is virtually planar, with a dihedral angle between the fused five- and six-membered rings of 1.17 (4)degrees. The methylpiperazine ring adopts a chair conformation. In the crystal structure, intermolecular C-H center dot center dot center dot O and C-H center dot center dot center dot N hydrogen bonds link the molecules, generating edge-fused R-3(3)( 17) ring motifs, to form a three-dimensional network.
