Hydrazine → 5-(5-chloro-1-(6-chloropyridin-3-yl)pentyl)-N-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenyl)-1H-1,2,4-triazol-3-amine

Participants

Reaction Steps

Methyl 4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenylcarbamimidothioate, hydroiodide (500 mg, 1.69 mmol, from preparation A) and 6-chloro-2-(6-chloropyridin-3-yl)hexanoic acid (442 mg, 1.69 mmol, from preparation AJ) 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-(6-chloropyridin-3-yl)pentyl)-N-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenyl)-1H-1,2,4-triazol-3-amine (190 mg, 0.375 mmol, 23% yield) as a pink foam. LC-MS (M+H)+ 508.1.
