Procedure: 2-Bromo-5-fluoro-aniline (5.00 g, 95 mass % article, 25.0 mmol), m-nitrobenzenesulfonic acid (2.65 g, 13.0 mmol), 20.0 mL of 85 wt % aqueous phosphoric acid solution and ferrous sulfate heptahydrate (65.5 mg, 0.250 mmol) were placed in a 100 mL three-neck flask equipped with a magnetic stirrer, a reflux condenser, a thermometer and a dropping funnel and the mixture was heated to 80° C. in an oil bath. Subsequently, trans-2-hexenal (6.51 g, 98 mass % article, 65.0 mmol) was added dropwise thereto through the dropping funnel for 1 hour. After completion of the dropwise addition, the mixture was heated and stirred at 100° C. for 2 hours. Then, the reaction mixture was poured into water and neutralized to pH 7 by ammonia water. The neutralized liquid was extracted with dichloromethane, and then dichloromethane was removed under reduced pressure. The resulting crude reaction product was purified by column chromatography (Hexane/AcOEt=100/0→1/10) using silica gel, followed by drying under reduced pressure to give 625 mg of 8-bromo-5-fluoro-2-propylquinoline as a yellowish white solid (yield: 9.33%). equipped with a magnetic stirrer, a reflux condenser After completion of the dropwise addition the mixture was heated The neutralized liquid was extracted with dichloromethane dichloromethane was removed under reduced pressure The resulting crude reaction product was purified by column chromatography (Hexane/AcOEt=100/0→1/10) by drying under reduced pressure
