Methanaminium, N-((dimethylamino)(3H-1,2,3-triazolo(4,5-b)pyridin-3-yloxy)methylene)-N-methyl-, hexafluorophosphate(1-) (1:1) → 4-({[(3-Fluoro-4-methylphenyl)amino]carbonyl}amino)-N-[1-(6-methoxypyridin-3-yl)ethyl]-1-methyl-1H-imidazole-2-carboxamide

Participants

Reaction Steps

60 mg (0.2 mmol) of 4-({[(4-methyl-3-fluorophenyl)amino]carbonyl}amino)-1-methyl-1H-imidazole-2-carboxylic acid (Example 18A) are dissolved in 4 ml of DMF and, after addition of 150 mg (0.39 mmol) of HATU and 36 mg (0.3 mmol) of DMAP, stirred at room temperature for 15 minutes. 60 mg (0.39 mmol) of [1-(6-methoxypyridin-3-yl)ethyl]amine are added to this solution and the mixture is stirred overnight. The reaction mixture is purified by preparative HPLC. The correct fractions are evaporated in vacuo.
