Abstract:
Six novel 4-arylamino-6-fluoroquinazolines such as 4-[4-((E)-3,4,5-trimethoxystyryl)]anilino-6-fluoroquinazoline etc. were synthesized from 6-fluoro-4-chloroquinazoline and trans-aminostilbene derivatives in yields of 55%~76%. Their chemical structures were identified by 1H NMR, IR and elemental analysis. The 1H NMR analysis showed that the single peak in the δ 9.74~9.79 ppm was produced by the—NH of the 4-position in the compounds; The IR analysis showed that the peak in 3 618~3 278 cm-1 also proved the formation of the target compounds.
