Methyl N′-2-(4-fluorophenyl)pent-4-enoyl-N-(3-methoxy-4-(3-methyl-1H-1,2,4-triazol-1-yl)phenyl)carbamimidothioate (0.62 g, 1.367 mmol) was reacted with allylhydrazine (70% solution in water, 0.55 mL, 5.47 mmol) using a procedure analogous to Step B of Example 1 to provide 1-allyl-5-(1-(4-fluorophenyl)but-3-enyl)-N-(3-methoxy-4-(3-methyl-1H-1,2,4-triazol-1-yl)phenyl)-1H-1,2,4-triazol-3-amine. The purified product was dissolved in 0.1% TFA/dichloromethane and reconcentrated to afford 1-allyl-5-(1-(4-fluorophenyl)but-3-enyl)-N-(3-methoxy-4-(3-methyl-1H-1,2,4-triazol-1-yl)phenyl)-1H-1,2,4-triazol-3-amine, TFA salt (446 mg, 0.692 mmol, 51% yield) as a clear solid residue. LC-MS (M+H)+=560.3.
