Synthesis, Crystal Structure, and Theoretical Studies of N-(4-((4-chlorobenzyl)oxy)phenyl)-4- (trifluoromethyl)pyrimidin-2-amine
The title compound (C18H13ClF3N3O) were synthesized and recrystallized from CH3OH. The compound was characterized byH1NMR, MS, HRMS, and X-ray diffraction. The compound crystallized in the monoclinic space groupP2(1)/nwitha=8.2354(14),b=12.686(2),c=16.633(3) Å,α=90,β=97.951(3),γ=90∘,V=1721.0(5) Å3,Z=4,andR=0.0376for 1933 observed reflections withI>2σ(I).X-ray analysis reveals that intermolecular N–H⋯N interactions exist in the adjacent molecules. Theoretical calculation of the title compound was carried out with HF/6-31G(d,p), B3LYP/6-31G(d,p). The full geometry optimization was carried out using 6-31G(d,p)basis set and the frontier orbital energy. The optimized geometric bond lengths and bond angles obtained by using HF and DFT (B3LYP) showed the best agreement with the experimental data.
