Procedure

To a solution of 4-(4-amino-2-fluorophenoxy)picolinamide (Compound B′ of Example 24, 1.0 g, 4.0 mmol) in DMF (10.0 mL) were added DIEA (2.0 mL) and ethyl 3-chloro-3-oxopropanoate (Aldrich, 0.75 mL, 6.0 mmol). The mixture was stirred at room temperature for 12 h and more ethyl 3-chloro-3-oxopropanoate (0.20 mL, 1.6 mmol) was added. The mixture was stirred for 2 h and was then diluted with EtOAc (200 mL). It was washed with H2O and brine and then dried over MgSO4. After filtration and concentration, the residue was triturated with DCM and filtered to give ethyl 3-(4-(2-carbamoylpyridin-4-yloxy)-3-fluorophenylamino)-3-oxopropanoate (900 mg, 62% yield). MS (ESI+) m/z 362.28 (M+H)+.
