To a suspension of 6-(3-(tert-butyldimethylsilyloxy)propyl)-N-(3-chloro-4-fluorophenyl)-2-(pyridin-3-yl)quinazolin-4-amine (0.35 g, 0.67 mmol) in MeOH (10 mL) was added 1-chloroethyl chloroformate (7.2 μl, 0.067 mmol). The mixture was stirred overnight at room temperature. Methanol was removed in vacuo. Sat. NaHCO3 aqueous (10 mL) and CH2Cl2 (10 mL) were added to the residue and stirred for a while. The resultant solid was collected by filtration and dried to give 0.25 g of 3-(4-(3-chloro-4-fluorophenylamino)-2-(pyridin-3-yl)quinazolin-6-yl)propan-1-ol as light yellow solid (91%). MS i/z=409 (M+1) (Method D) (retention time=1.71 min), 1H NMR (300 MHz, DMSO) δ 10.01 (s, 1H), 9.51 (s, 1H), 8.66 (m, 2H), 8.37 (s, 1H), 8.29-8.20 (m, 1H), 7.94-7.67 (m, 3H), 7.63-7.43 (m, 2H), 4.60 (t, J=5.0 Hz, 1H), 3.56-3.35 (m, 2H), 2.94-2.69 (m, 2H), 2.15-1.56 (m, 2H).
