الإجراء التجريبي

Ethyl 2-[3-(3,4,5-trichlorophenyl)-3-(trifluoromethyl)pyrrolidin-1-yl]-4-(tri-fluoromethyl)-1,3-thiazole-5-carboxylate (2.4 g) was added to a mixture solution comprising 1,4-dioxane (40 mL) and an aqueous solution (40 mL) of sodium hydroxide (2.0 g), followed by heating at 80° C. for ten hours. After cooling, the reaction solution was poured over ice water, acidified by adding concentrated hydrochloric acid, and then extracted with ethyl acetate. The organic layer was dried over magnesium sulfate. The solvent was evaporated off under reduced pressure to obtain the title compound (2.25 g, 99%).
