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-difluorophenyl)hexanoic acid (443 mg, 1.69 mmol, from preparation AG) 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 product, 5-(5-chloro-1-(2,4-difluorophenyl)pentyl)-N-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenyl)-1H-1,2,4-triazol-3-amine (1.03 g, 100% yield), was used in the subsequent step without purification. LC-MS (M+H)+ 507.3.
