Methyl 4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenylcarbamimidothioate, hydroiodide (500 mg, 1.685 mmol, from preparation A) and 6-chloro-2-(2,4-dichlorophenyl)hexanoic acid (498 mg, 1.685 mmol, from preparation AG) were coupled and then reacted with hydrazine (0.212 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-(2,4-dichlorophenyl)pentyl)-N-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenyl)-1H-1,2,4-triazol-3-amine (173 mg, 0.272 mmol, 16% yield) as a pink foamy solid. LC-MS (M+H)+ 539.0.
