Reaction Steps

A mixture of Example C3 (0.377 g, 0.873 mmol) and K2CO3 (0.362 g, 2.62 mmol) in dioxane (4 mL) and water (1 mL) was sparged with Ar, treated with 2-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (0.201 g, 0.917 mmol) and Pd(Ph3P)4 (0.101 g, 0.087 mmol), sparged again with Ar and heated at 80° C. overnight. The mixture was cooled to RT, diluted with EtOAc, dried over Na2SO4, concentrated to dryness and purified via silica gel chromatography (MeOH/EtOAc). The material was treated with Et2O, stirred at RT and the resulting solid collected via filtration and dried to afford N-(6-methyl-5-((2′-methyl-[2,4′-bipyridin]-4-yl)oxy)pyridin-2-yl)-2-oxo-3-(tetrahydro-2H-pyran-4-yl)imidazolidine-1-carboxamide (151 mg, 35%). 1H NMR (400 MHz, DMSO-d6): δ 10.90 (s, 1 H), 8.56 (d, J=5.6 Hz, 1 H), 8.52 (d, J=5.2 Hz, 1 H), 7.93-7.88 (m, 2 H), 7.79 (dd, J=5.3, 1.6 Hz, 1 H), 7.66-7.63 (m, 2 H), 6.86 (dd, J=5.6, 2.4 Hz, 1 H), 3.93-3.77 (m, 5 H), 3.49-3.34 (m, 4 H), 2.52 (s, 3 H), 2.26 (s, 3 H), 1.78-1.66 (m, 2 H), 1.63-1.57 (m, 2H); MS (ESI) m/z: 489.2 (M+H+).
