Reaction Steps

To a solution of 5-[5-amino-2-(2,4-difluorophenoxy)phenyl]-1-methylpyridin-2-one (30 mg, 0.09 mmol) in DCM (4 mL) was added TEA (27.3 mg, 0.27 mmol) and EtSO2Cl (35.39 mg, 0.27 mmol). The mixture was stirred at 30° C. for 12 h. Water (4 mL) was added and the mixture was extracted with DCM (4 mL×3). The organic layer was concentrated and the residue was purified by prep-HPLC to give the title compound (10 mg, 26%) as light yellow gum. 1H NMR (CDCl3, 400 MHz) δ7.68-7.66 (m, 2H), 7.28 (d, J=2.4 Hz, 1H), 7.13-7.10 (m, 1H), 7.09 (s, 1H), 7.00-6.92 (m, 2H), 6.84-6.86 (m, 1H), 6.78 (d, J=8.4 Hz, 1H), 6.73 (d, J=9.2 Hz, 1H), 3.65 (s, 3H), 3.14 (q, J=7.2 Hz, 2H), 1.41 (t, J=7.2 Hz, 3H). LCMS (M+H)+ 421.
