A solution of 5-(5-chloro-1-(4-(2,2,2-trifluoroethoxy)phenyl)pentyl)-N-(3-fluoro-4-(5-methyl-1H-1,2,4-triazol-1-yl)phenyl)-1H-1,2,4-triazol-3-amine (2.11 g, 3.92 mmol), sodium iodide (2.94 g, 19.6 mmol), and diisoproplylethylamine (0.685 mL, 3.92 mmol) in acetone (30 mL) was heated in a sealed vessel at 100° C. for 12 h. The reaction was concentrated in vacuo. The crude product was purified using silica gel column chromatography (50% EtOAc/chloroform) to afford 770 mg (38% yield) of the titled compound as an off-white solid. This material was recrystallized from EtOH (20 mL) to afford 424 mg (22% yield) of the titled compound as a crystalline white solid.
