A solution of 5-(5-chloro-1-(4-(2,2-difluoroethoxy)phenyl)pentyl)-N-(4-(3,5-dimethyl-1H-1,2,4-triazol-1-yl)-3-fluorophenyl)-1H-1,2,4-triazol-3-amine (787 mg, 1.47 mmol), sodium iodide (1.10 g, 7.37 mmol), and diisopropylethylamine (1.29 mL, 7.37 mmol) in acetone (30 mL) was heated in a sealed vessel at 100° C. for 3 h. The reaction was concentrated in vacuo. After an aqueous workup, the crude organic concentrate was purified using reverse phase preparatory HPLC (MeOH/water/TFA) to afford 145 mg (16% yield) of the titled compound as the TFA salt.
