Reaction Steps

A solution of 3-((2-chloropyridin-4-yl)oxy)-6-iodo-2-methylpyridine (8.5 g, 24.53 mmol) in dioxane (100 mL) was sparged with argon, treated with acetamide (5.07 g, 86 mmol), Cs2CO3 (11.99 g, 36.8 mmol), X-Phos (0.585 g, 1.226 mmol) and Pd2(dba)3 (1.123 g, 1.226 mmol) and heated at 83° C. for 16 h. The mixture was cooled to RT, treated with EtOAc, solids removed via filtration through diatomaceous earth, rinsed well with EtOAc, and the filtrate washed with H2O, then brine, dried over Na2SO4, concentrated to dryness and purified via silica gel chromatography (EtOAc/Hex) to afford N-(5-((2-chloropyridin-4-yl)oxy)-6-methylpyridin-2-yl)acetamide (3.8 g, 56%) as an off-white solid. MS (ESI) m/z: 278.0 (M+H+).
