実験手順: 11 g of potassium carbonate was added to a dimethylformamide (150 ml) solution of 10.7 g of methyl 5-fluoro-2-nitrobenzoate and 11.1 g of 4-(ethylsulfonyl)phenol obtained from Reference Example 2, and stirred under heat at 80° C. for 90 minutes. The reaction liquid was restored to room temperature, then 300 ml of water was added to it, and the formed solid was taken out through filtration. This was dried under reduced pressure to obtain 19.7 g of the entitled compound as a creamy white solid. The reaction liquid was restored to room temperature the formed solid was taken out through filtration This was dried under reduced pressure

実験手順: 3.5 g of potassium carbonate was added to a dimethylformamide (110 ml) solution of 6 g of methyl 2-fluoro-5-nitro-4-[(2-pyridinylcarbonyl)amino]benzoate and 3.48 g of 4-(ethylsulfonyl)phenol obtained in Reference Example 2, and stirred under heat at 80° C. for 30 minutes. The reaction liquid was restored to room temperature, poured into 300 ml of water, and the formed solid was taken out through filtration. This was dried under reduced pressure to obtain 7.46 g of the entitled compound as a yellow solid. obtained in Reference Example 2 The reaction liquid was restored to room temperature the formed solid was taken out through filtration This was dried under reduced pressure
