2-{4-[(1,3-Benzodioxol-5-yl)methyl]piperazin-1-yl}pyrimidine

Abstract

In the title compound, C16H18N4O2, known also as peribedil, the dihedral angle between the mean planes of the pyrimidine and benzene rings is 56.5 (8)°. The 1,3-dioxole fragment adopts an envelope conformation with the methylene C atom forming the flap; this atom deviates by 0.232 (3) Å from the plane defined by the remaining atoms of the 1,3-benzodioxole unit. In the crystal, C—H...π interactions between c-glide-related molecules arrange them into columns extending along the c-axis direction. The columns related by a unit translation along the b axis are packed into (100) layers via another C—H...π interaction involving the pyrimidine ring as an acceptor.
