Reaction Steps

(4-Ethynyl-pyridin-2-yl)-urea (75 mg, 0.47 mmol), 4-fluoro-1-iodo-2-methyl-benzene (224 mg, 0.931 mmol), triethylamine (5.0 mL), palladium bis(triphenylphosphine)dichloride (16 mg, 0.023 mmol) and Copper (I) iodide (8.8 mg, 0.047 mmol) are mixed in DMF (1.8 mL). The reaction mixture is stirred for 16 hrs at room temperature before saturated NH4Cl solution (5 mL) is added along with water (25 mL). The mixture is extracted with EtOAc (3×20 mL) and the organic layers are combined and concentrated to give the crude product. Purification by silica flash column chromatography using MeOH in DCM (gradient from 0% to 5%) affords 25 mg of the desired product.
