Participants

Reaction Steps

1,1-Carbonyldiimidazole (9.78 g) dissolved in dioxane (100 ml) is added dropwise to 6-acetylaminopyridine-2-carboxylic acid (10.86 g) in a mixture of dioxane (100 ml) and DMF (60 ml) and the mixture is stirred at room temperature for 3 h. N-{3-[({4-[(Z)-Amino(hydroxyimino)methyl]phenyl}sulfonyl)amino]phenyl}acetamide is then added as a solid and the reaction mixture is stirred at room temperature for 16 h. Subsequently, the reaction mixture is stirred at 100° C. for 4 h and then poured onto ice/water. The product is left to stand for 10 min, collected by filtration, washed with water (three times) and dried in a vacuum oven. 25.55 g (90% of theory) of product are obtained as a solid.
