Procedure

To a mixture of a solution of NaHCO3 (47 mg in 1.5 mL, 0.561 mmol) and ethyl acetate (3 mL), 2,2-difluoroethyl trifluoromethanesulfonate (48 μL, 0.22 mmol) was added. After heating at 40 C, (S)-1-(5-tert-butylisoxazol-3-yl)-3-(3-(7-methoxy-6-(pyrrolidin-3-yloxy)quinazolin-4-yloxy)phenyl)urea dihydrochloride (110 mg, 0.187 mmol) was added. The reaction mixture was stirred at 40° C. for 1 h. The mixture was diluted with ethyl acetate and organic layer was washed with brine. After drying over MgSO4, the solvent was evaporated and the crude product purified on silica gel, using dichloromethane/methanol as mobile phase. Yield: 40 mg (37%). 1HNMR (dmso-d6): δ 9.58 (1H, s), 9.00 (1H, s), 8.56 (1H, s), 7.59 (1H, s), 7.47 (1H, s), 7.40 (2H, m), 7.25 (1H, d), 6.97 (1H, d), 6.48 (1H, s), 5.15 (1H, m), 5.15 (1H, m), 3.99 (3H, s), 2.91 (6H, m), 2.40 (1H, m), 1.90 (1H, m), 1.27 (9H, s). LC-MS (ESI) m/z 583 (M+H)+.
