The lead compound 4-(3′-bromobenzoyl)-6,7-dimethoxyquinazoline WHI-P164 was synthesized by reacting 4-chloro-6,7-dimethoxyquinazoline 5 with the commercially available 3-bromobenzaldehyde in the presence of 1,3-dimethylimidazolium iodide and sodium hydride in refluxing dioxane for 4 hours (Scheme 2) (32,33). The remaining 6,7-dimethoxyquinazoline derivatives were synthesized by condensing 4-chloro-6,7-dimethoxyquinazoline 5 with the corresponding substituted anilines as shown in Scheme 3.
