Procedure

To a stirred solution of 3-[1-(2,6-dichloro-3-fluoro-phenyl)-ethoxy]-5-iodo-pyridin-2-ylamine (100 mg, 0.23 mmol) and 3-methyl-1H-pyrazole (59 mg, 0.70 mmol) in DMSO (1 mL was added K3PO4 (101 mg, 0.47 mmol), dodecane (0.015 mL, 0.05 mmol), cyclohexanediamine (0.009 mL, 0.07 mmol) and copper iodide (CuI) (14 mg, 0.07 mmol). The solution was bubbled with nitrogen for 5 minutes, then radiated with microwave at 150° C. for 2 hours, LCMS checked that the reaction was completed, the mixture was purified by prep-HPLC to leave 3-[1-(2,6-dichloro-3-fluoro-phenyl)-ethoxy]-5-(3-methyl-pyrazol-1-yl)-pyridin-2-ylamine (30 mg), yield 34.2%
