A solution of 5-(5-chloro-1-(2-fluorophenyl)pentyl)-N-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenyl)-1H-1,2,4-triazol-3-amine (2.47 g, 5.05 mmol), sodium iodide (3.79 g, 25.3 mmol), and diisoproplylethylamine (1.77 mL, 10.1 mmol) in acetone (40 mL) was heated in a sealed vessel at 100° C. for 2 h. The reaction was concentrated in vacuo. The crude product was purified using silica gel column chromatography (0-35% EtOAc/chloroform, linear gradient) to afford 234 mg (10% yield) of the titled compound as a pale yellow solid. The solid was recrystallized from EtOH to afford an analytical sample.
