A novel type of quinazoline derivatives, which were designed by the combination of quinazoline as the backbone and oxazole scaffold as the substituent, have been synthesized and their biological activities were evaluated for anti‐proliferative activities and EGFR inhibitory potency. Compound 12b demonstrated the most potent inhibitory activity (IC50=0.95 µmol/L for EGFR), which could be optimized as a potential EGFR inhibitor in the further study. The structures of the synthesized quinazoline analogs and all intermediates were comfirmed by 1H and 13C NMR, 2D NMR spectra, IR spectra and MS spectra.

In the crystal structure of the title amino alcohol derivitive, C12H19NO2, mol­ecules are linked by N—H⋯O hydrogen bonds. The mol­ecular structure exhibits an intra­molecular O—H⋯N hydrogen bond.
