摘要

In our recent efforts to explore variation at positions 6 and 7 of the ring nucleus to further investigate the structure–activity, it was shown that 4-(3-chloro-4-fluoroanilino)-6-alkoxy-7-aminoquinazolines were inhibitors of the tyrosine kinase activity of EGFR. Herein, we communicate the facile and parallel chemistry employed to achieve this important class of kinase inhibitors from their corresponding 7-triflates (Scheme 1). ... Synthesis of the 7-triflates 3 and 5. Reagents and conditions: (i) ...
