A mixture of 1,1,1-trifluoro-4-[5-fluoro-2-(methyloxy)phenyl]-4-methyl-2-[({6-methyl-1-[3-(methyloxy)phenyl]-1H-indazol-4-yl}amino)methyl]-2-pentanol (Example 22, 137 mg, 0.25 mmol) and lithium iodide (1 g, 7.5 mmol) in N-methylpyrrolidinone (6 mL) was heated in a microwave at 220° C. for 55 minutes. The solvent was removed using a vacuum centrifuge and the residue was partitioned between water (25 mL) and dichloromethane (50 mL) and passed through a hydrophobic frit. The organic filtrate was evaporated under reduced pressure and purified by silica gel chromatography (20 g cartridge) eluting with a 100:0 to 0:100 gradient of cyclohexane:ethyl acetate over 30 minutes to give the title compound (41 mg).
