To a solution of Intermediate 48 (15.8 mg, 0.048 mmol) was added DMF (0.4 mL), 4-chloro-2,6-dimethylpyrimidine (8.2 mg, 0.057 mmol) and cesium carbonate (38.8 mg, 0.119 mmol). The mixture was heated to 100° C. for 18 hours, diluted with water and extract with ethyl acetate. The organic layer was dried over Na2SO4 and concentrated. The residue was purified by reverse phase HPLC to give the title compound (12.9 mg, 62%). MS (ESI): mass calculated for C23H24FN5OS, 437.5; m/z found [M+H]+438.2. 1H NMR (400 MHz, CDCl3): 7.51-7.41 (m, 2H), 7.06-6.95 (m, 2H), 6.29 (s, 1H), 3.892-3.76 (m, 2H), 3.73-3.51 (m, 3H), 3.44 (dd, J=11.6, 5.0 Hz, 1H), 3.32 (dd, J=11.6, 4.5 Hz, 1H), 3.10 (dd, J=11.3, 5.3 Hz, 1H), 3.02-2.80 (m, 2H), 2.70 (s, 3H), 2.31 (d, J=20.0 Hz, 6H).
