3-Methyl-5-(4-methylpiperazin-1-yl)-1-phenyl-1H-pyrazole-4-carbaldehyde

Abstract

In the title compound, C16H20N4O, the dihedral angle between the pyrazole and phenyl rings is 53.86 (12)°. The piperazine ring adopts a chair conformation with the exocyclic N—C bonds in equatorial orientations. In the crystal, molecules are linked by very weak C—H...O hydrogen bonds to generate [010] C(8) chains, with adjacent molecules related by translation.
