Procedure
A mixture of Example C8 (1 g, 2.131 mmol), t-butyl carbamate (0.749 g, 6.39 mmol), Cs2CO3 (2.083 g, 6.39 mmol) and Xantphos (0.555 g, 0.959 mmol) in dioxane (15 mL) was sparged with Ar, treated with Pd2(dba)3 (0.293 g, 0.320 mmol), sparged again with Ar and heated at 100° C. overnight. The mixture was cooled to RT, treated with satd. NaHCO3, extracted with EtOAc (3×) and the combined organics were dried over Na2SO4, passed through a pad of silica gel and concentrated to dryness to afford crude tert-butyl (4-(2-chloro-5-fluoro-4-(2-oxo-3-(tetrahydro-2H-pyran-4-yl)imidazolidine-1-carboxamido)phenoxy)pyridin-2-yl)carbamate (1.32 g, 113%) which was used without further purification. MS (ESI) m/z: (M+H+): 550.1.
