Methyl 4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenylcarbamimidothioate, hydroiodide (1.50 g, 3.53 mmol, from preparation A) and 6-chloro-2-(4-(2,2,2-trifluoroethoxy)phenyl)hexanoic acid (1.43 g, 4.42 mmol, from preparation AW) were coupled [N-methylmorpholine (2.00 mL, 17.7 mmol) was substituted for N,N-diisopropylethylamine] and then reacted with hydrazine (0.556 mL, 17.7 mmol) using a procedure analogous to Step A of Example 13. After an aqueous workup, 5-(5-chloro-1-(4-(2,2,2-trifluoroethoxy)phenyl)pentyl)-N-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenyl)-1H-1,2,4-triazol-3-amine was obtained as a brown foamy solid. LC-MS (M+H)+ 569.3. The crude product was used in the next step without purification.
