Reaction Steps

A solution of Example C1 (0.15 g, 0.4 mmol) and 2-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (0.13 g, 0.57 mmol) in dioxane (4 mL) was sparged with Ar, treated with a solution of K2CO3 (0.11 g, 0.8 mmol) in water (1 mL) and heated at 90° C. for 2 h. The mixture was cooled to RT, diluted with water, extracted with EtOAc (3×) and the combined organics were washed with brine, dried over Na2SO4, concentrated to dryness and purified by silica gel chromatography (MeOH/DCM) to afford N-ethyl-4-methoxy-5-(6-methyl-5-((6′-methyl-[2,3′-bipyridin]-4-yl)oxy)pyridin-2-yl)pyrimidin-2-amine as an orange foam (0.106 g, 61%). 1H NMR (400 MHz, DMSO-d6): δ 9.11 (d, J=2.4 Hz, 1H), 8.74 (s, 1H), 8.54 (d, J=5.7 Hz, 1H), 8.29 (dd, J=8.1, 2.4 Hz, 1H), 7.77 (d, J=8.6 Hz, 1H), 7.65 (d, J=2.4 Hz, 1H), 7.59 (d, J=8.6 Hz, 1H), 7.34 (d, J=8.2 Hz, 1H), 7.02 (d, J=1.9 Hz, 1H), 6.79 (dd, J=5.7, 2.4 Hz, 1H), 3.96 (s, 3H), 3.36-3.34 (m, 2H), 2.51 (s, 3H), 2.38 (s, 3H), 1.15 (s, 3H); MS (ESI) m/z: 429.2 (M+H+).
