Methyl 4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenylcarbamimidothioate, hydroiodide (0.500 g, 1.18 mmol), from preparation A) and 6-chloro-2-(4-ethoxyphenyl)hexanoic acid (0.351 g, 1.30 mmol, from preparation AAN) were coupled [N-methylmorpholine (0.647 mL, 5.89 mmol) was substituted for N,N-diisopropylethylamine] and then reacted with hydrazine (0.148 mL, 4.71 mmol) using a procedure analogous to Step A of Example 13. After an aqueous workup, 5-(5-chloro-1-(4-ethoxyphenyl)pentyl)-N-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenyl)-1H-1,2,4-triazol-3-amine was obtained as a brown residue. The crude product was used in the next step without purification. LC-MS (M+H)+ 515.1.
