growth factor receptor (EGFR) tyrosine kinase inhibitors were designed and synthesized. All structures of the compounds were characterized by 1H‐NMR, 13C‐NMR, and high‐resolution mass spectrometry. The inhibition activities of the target compounds for the EGFR tyrosine kinase activity in vitro were determined. Compounds 6a, 6b, 6c, 6d displayed moderate activity in targeting EGFR.
