Procedure

To a solution of 2-(4-fluorophenyl)-N-methylacetamide (89 mg, 0.53 mmol) in 2 mL of THF at −78° C. was added MeLi in Et2O (1.6 M, 0.34 mL, 0.55 mmol). The solution was stirred at −78° C. for 5 min and then 20% phosgene in toluene (1.9 M, 0.29 mL, 0.55 mmol) was introduced quickly. After 2 min, 4-(4-amino-2-fluorophenoxy)picolinamide (Compound B′ of Example 24, 100 mg, 0.40 mmol) was added, followed by the addition of DMF (2 mL) and DIEA (0.4 mL). The reaction mixture was stirred at room temperature for 1 h and quenched with H2O. The solution was then extracted with EtOAc and the organic layer was washed with brine, dried over MgSO4. After filtration and concentration, the residue was purified by silica gel chromatography to give the title compound (77 mg, 33%). MS(ESI+) m/z 441 (M+H)+.
