To a degassed solution of 2-chloro-N-(3-cyano-1-phenyl-1H-pyrazol-5-yl)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzamide (Preparation 7, 325 mg, 0.72 mmol), 2-chloro-3-fluoro-6-(methoxymethyl)pyridine (Preparation 52, 191 mg, 1.09 mmol) and potassium carbonate (200 mg, 1.45 mmol) in 1,4-dioxane (5 mL) and water (1 mL) was added Pd(PPh3)4 (83 mg, 0.072 mmol) and the reaction was heated to 80° C. for 18 hours. The reaction was cooled and concentrated in vacuo. The resulting residue was partitioned between EtOAc (15 mL) and water (15 mL). The aqueous layer was extracted with EtOAc (2×15 mL) and the organic extracts were combined, dried over sodium sulphate and concentrated in vacuo. The residue was purified using silica gel column chromatography eluting with 1:1 EtOAc in heptanes to afford the title compound (250 mg, 75%).
