Procedure
A suspension of Example B8 (0.074 g, 0.673 mmol) in DCE (4 mL) was treated with oxalyl chloride (0.059 mL, 0.673 mmol), stirred at RT for 1 h, then heated to 80° C. for 1.5 h. The mixture was cooled to RT, added drop-wise to a solution of Example A2 (0.15 g, 0.561 mmol) and pyridine (0.226 mL, 2.81 mmol) in THF (4 mL) and stirred at RT overnight. The mixture was treated with satd. NaHCO3, extracted with EtOAc (4×) and the combined organics were dried over Na2SO4, concentrated to dryness and purified via silica gel chromatography (MeOH/DCM) to afford 1-cyano-N-((5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)carbamoyl)cyclopropanecarboxamide (176 mg, 78%) as an off-white solid. MS (ESI) m/z: 404.1 (M+H+).
