Procedure

To a solution of (S)-1-(5-tert-butylisoxazol-3-yl)-3-{3-[6-methoxy-7-(pyrrolidin-3-yloxy)quinazolin-4-yloxy]phenyl}urea (0.198 g, 0.38 mmol) and N,N-diisopropylethylamine (0.5 mL) in CH2Cl2 (10 mL) was added 2,2-difluoroethyl trifluoromethanesulfonate (0.128 g. 0.6 mmol) and it was stirred at 40° C. for 1 hour. It was quenched with saturated NaHCO3 and extracted with CH2Cl2. Extracts were dried over MgSO4 and concentrated under reduced pressure. It was purified by silica gel chromatography with 70-85% EtOAc/hexane as eluants to afford (S)-1-(5-tert-Butylisoxazol-3-yl)-3-(3-{7-[1-(2,2-difluoroethyl)pyrrolidin-3-yloxy]-6-methoxyquinazolin-4-yloxy}phenyl)urea as solid (0.098 g, 44%). 1H NMR (300 MHz, CDCl3) δ 9.4 (s, 1H), 8.62 (s, 1H), 7.81 (s, 1H), 7.65 (t, 1H), 7.54 (s, 1H), 7.40 (t, 1H), 7.33 (m, 1H), 7.19 (s, 1H), 7.00 (d, 1H), 5.93 (tt, 1H), 5.87 (s, 1H), 5.05 (m, 1H), 4.03 (s, 3H), 3.20 (m, 1H), 3.89-3.09 (m, 4H), 2.8 (m, 1H), 2.5 (m, 1H), 2.15 (m, 1H), 1.33 (s, 9H); LC-MS (ESI) m/z 583 (M+1-1)+.
