Reaktionsschritte

To a solution of pyrimidine-4-carboxylic acid (1.0 g, 8.0 mmol) in THF (15 mL), N,N-Carbonyldiimidazole (1.4 g, 8.9 mmol) was added. After refluxing for 2 hours, hydrazine (0.8 g, 20 mmol) was added to the reaction mixture slowly with a syringe at 0° C. The reaction mixture was allowed to warm to room temperature slowly and then concentrated to yield the desired product as white solid. LCMS calculated for C5H7N4O (M+H): 139.1; found: 139.1.
