title: 3-(2,4-Dichloro-phen-yl)-5-(4-fluoro-phen-yl)-2-methyl-7-(trifluoro-meth-yl)pyrazolo-[1,5-a]pyrimidine.
abstract: In the title compound, C(20)H(11)Cl(2)F(4)N(3), the central pyrazolo-[1,5-a]pyrimidine unit is almost planar [the mean deviation from the best least-square plane through the nine atoms is 0.006 (2) Å]. The fluoro-benzene ring is rotated out of this plane by 10.3 (3)°, whereas the dichloro-benzene ring is rotated by 46.2 (3)°. The crystal packing is dominated by Cl⋯Cl inter-actions of 3.475 (3) Å and van der Waals inter-actions.
