With cooling with ice, 110 ml of fuming nitric acid was gradually added to 27.7 g of methyl 2-fluoro-4-[(2-pyridinylcarbonyl)amino]benzoate, and stirred at room temperature for 1.5 hours. With cooling with ice, the reaction liquid was gradually added to a solution of sodium carbonate (138 g) in water (2000 ml), and the formed solid was taken out through filtration. This was dried under reduced pressure to obtain 27.5 g of the entitled compound as a yellow solid.
