실험 절차
A suspension of 70.70 g of cloquintocet-mexyl (96.9% strength) in 205 g of demineralised water was stirred at 100° C. in a 1 L jacketed glass vessel. 27.5 g of aqueous hydrochloric acid [32%] was slowly added, and the reaction mixture was stirred under reflux for 6 hours. The biphasic solution was then cooled down to 20° C. over 4 hours and the resulting suspension was filtered and the solid was wash with 2×50 mL of demineralised water and dried. Cloquintocet acid hydrochloride (35.55 g) was isolated as a light brown solid.
