- Example 7 Synthesis of compound (IV) To a mixture of 5 g of compound (V) and 28.3 g of dimethylformamide (water content: about 953 ppm), 5.48 g of ammonium peroxodisulfate was added at 60°C to obtain a reaction mixture. The resulting reaction mixture was stirred at the same temperature for 1 hour. A reaction check was performed by HPLC to confirm that compound (IV) was produced. After the conventional post-treatment described above, compound (IV) was obtained.
- Example 8 Synthesis of isopropyl 3-bromo-1-(3-chloropyridin-2-yl)-1H-pyrazole-5-carboxylate (hereinafter also simply referred to as compound (VII)) (1) 1 with a purity of 91.8 area% 5 g of isopropyl-(3-chloropyridin-2-yl)-3-hydroxy-4,5-dihydro-1H-pyrazole-5-carboxylate (remaining 9.2% is compound (VI)) and 3.9 g of acetonitrile A mixture of 3.3 g of phosphorus oxybromide and 3.9 g of acetonitrile was added dropwise to the mixture at room temperature to obtain a reaction mixture.
- reaction mixture was heated to the reflux temperature and stirred at the same temperature for 1 hour.
- the reaction was checked by HPLC, and isopropyl 3-bromo-1-(3-chloropyridin-2-yl)-4,5-dihydro-1H-pyrazole-5-carboxylate (hereinafter also simply referred to as compound (VIII) ) was generated at 91.0 area %.
- the reaction mixture was cooled to 26° C., and 5 g of water was slowly added dropwise at the same temperature to obtain a mixture. 7.6 g of a 20% sodium hydroxide aqueous solution was added to the mixture to adjust the pH to about 7.8, and the mixture was stirred at 20 to 30° C. for 20 minutes.
- the reaction mixture was cooled to 20° C., 48.8 g of a 5% aqueous sodium hydroxide solution was added at the same temperature to adjust the pH to about 8, and the mixture was stirred at 20-30° C. for 15 minutes. Then, acetonitrile was distilled off from the pH-adjusted mixture under normal pressure, and 4.3 g of a 10% aqueous sodium hydroxide solution was added to the mixture after distillation to adjust the pH to about 7. The resulting mixture was extracted with 63 g of ethyl acetate to obtain a mixture containing compound (V) and ethyl acetate.
