With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.6854-07-5, name is 5-Nitro-2-oxo-3-pyridinecarboxylic Acid, molecular formula is C6H4N2O5, molecular weight is 184.11, as common compound, the synthetic route is as follows.Recommanded Product: 6854-07-5

Step B 2-Methoxy-3-carbomethoxy-5-nitropyridine 2-Hydroxy-3-carboxy-5-nitropyridine was converted to 2-chloro-3-chlorocarbonyl-5-nitropyridine in situ and converted to the title compound by reaction with anhydrous methanol according to the procedure of A. Monge et al J. Het. Chem. (29), 1545 (1992). In a 500 mL was added starting material (10.2 g, 54 mmol) in 200 mL of chlorobenzene.
