✦ Synopsis
The title compound, C 26 H 17 ClF 5 N 3 O 5 , belongs to a new class of amide compounds having potential biological activity. The pyrimidine ring makes a dihedral angle of 61.66 (2) with the adjacent benzene ring. The dihedral angle between the other two benzene rings is 73.12 (1) . There are intramolecular C-HÁ Á ÁO, C-HÁ Á ÁF, N-HÁ Á ÁO and N-HÁ Á ÁCl hydrogen bonds. One of the fluorophenyl groups is disordered over two positions in a ratio of ca. 3:1. The molecules are connected by intermolecular ClÁ Á ÁO non-bonded interactions [ClÁ Á ÁO = 3.054 (2) A ˚], forming a dimer.
