Reaction Steps

A solution of 5-(5-chloro-1-(4-(2,2,2-trifluoroethoxy)phenyl)pentyl)-N-(5-fluoro-4-(3-methyl-1H-1,2,4-triazol-1-yl)phenyl)-1H-1,2,4-triazol-3-amine (1.03 g, 1.91 mmol), sodium iodide (1.43 g, 9.54 mmol), and diisoproplylethylamine (0.1.67 mL, 9.54 mmol) in acetone (10 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 silica gel column chromatography (50% EtOAc/chloroform) to afford 480 mg (48% yield) of the titled compound as an off-white solid. This material was recrystallized from EtOH to afford 225 mg (23% yield) of the titled compound as a crystalline white solid, LC-MS (M+H)+ 502.4. 1H NMR (500 MHz, CHLOROFORM-d) δ ppm 8.39 (d, J=2.1 Hz, 1 H), 7.69 (dd, J=13.7, 2.1 Hz, 1 H), 7.60 (t, J=8.7 Hz, 1 H), 7.13 (d, J=8.2 Hz, 2 H), 7.01 (d, J=8.9 Hz, 1H), 6.95 (d, J=8.5 Hz, 2H), 6.80 (s, 1 H), 4.36 (q, J=8.2 Hz, 2 H), 4.28 (d, J=7.3 Hz, 1 H), 4.21-4.26 (m, 2 H), 2.50 (s, 3 H), 2.17-2.28 (m, 1 H), 2.04-2.14 (m, 1 H), 1.84-2.03 (m, 4 H).
