Methyl 4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenylcarbamimidothioate, hydroiodide (500 mg, 1.69 mmol, from preparation B) and 6-chloro-2-(4-(trifluoromethoxy)phenyl)hexanoic acid (523 mg, 1.685 mmol, from preparation AI) were coupled and then reacted with hydrazine (0.211 mL, 6.74 mmol) using a procedure analogous to Step A of Example 13. The crude products were purified using silica gel chromatography (40-100% ethyl acetate/chloroform) to afford 5-(5-chloro-1-(4-(trifluoromethoxy)phenyl)pentyl)-N-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenyl)-1H-1,2,4-triazol-3-amine (80 mg, 0.14 mmol, 9.0% yield) as a yellow residue. LC-MS (M+H)+ 555.1.
