To a 100 mL round bottom flask, 3-amino-5-bromo-pyridine-2-carboxylic acid (1 g, 0.0046 mol) and urea (2.768 g, 0.4629 mol) were added. The reaction mixture was stirred at 200° C. for 2.5 h. The reaction mixture was cooled, water was added and stirred to provide a precipitate. The precipitate was filtered and dried to provide the title compound [1 g, 91%]. This material was taken to the next step without any further purification.
