4-Methylmorpholine → 5-(5-chloro-1-(4-(trifluoromethoxy)phenyl)pentyl)-N-(2-fluoro-5-methoxy-4-(3-methyl-1H-1,2,4-triazol-1-yl)phenyl)-1H-1,2,4-triazol-3-amine

Reaction Steps

Allyl 2-fluoro-5-methoxy-4-(3-methyl-1H-1,2,4-triazol-1-yl)phenylcarbamimidothioate, hydrobromide (1.42 g, 3.54 mmol, from preparation U) and 6-chloro-2-(4-(trifluoromethoxy)phenyl)hexanoic acid (1.375 g, 4.43 mmol, from preparation AY) 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 purification by silica gel column chromatography, 5-(5-chloro-1-(4-(trifluoromethoxy)phenyl)pentyl)-N-(2-fluoro-5-methoxy-4-(3-methyl-1H-1,2,4-triazol-1-yl)phenyl)-1H-1,2,4-triazol-3-amine (570 mg, 1.03 mmol, 29% yield) as a foamy solid. LC-MS (M+H)+ 554.3.
