A solution of 5-(5-chloro-1-(3,5-difluorophenyl)pentyl)-N-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenyl)-1H-1,2,4-triazol-3-amine (855 mg, 1.685 mmol), sodium iodide (1.26 g, 8.43 mmol), and diisoproplylethylamine (0.589 mL, 3.37 mmol) in acetone (20 mL) was heated in a sealed vessel at 100° C. for 4 h. The reaction was concentrated in vacuo. The crude product was purified using reverse phase preparatory-HPLC (MeOH/water/TFA). The purified material was crystallized from methanol to afford 34 mg (4% yield) of the titled compound as a white solid.
