Reaction Steps

While bubbling nitrogen through a solution of picolinic acid (1.23 g, 0.01 mole) in 100 ml of tetrahydrofuran, solid 1,1'-carbonyldiimidazole (1.62 g, 0.01 mole) was added in portions. The reaction mixture was allowed to stir at room temperature for 5 hours. Then, a solution of 2-[(3-amino-2-pyridinyl)amino]acetamide (1.66 g, 0.01 mole) in acetonitrile was added in portions to the imidazolide solution and the reaction mixture was allowed to stir at room temperature overnight. The solvents were evaporated. The residue completely solidified upon standing. The solid was washed with methylene chloride and the solid was filtered off. The solid was recrystallized from ethyl acetate to give several crops of crystals, which were combined and recrystallized from ethyl acetate to give 0.52 g of title compound, mp 188°-90° C. with decomposition.
