YieldReaction ConditionsOperation in experiment
63% With potassium carbonate; In N,N-dimethyl-formamide; at 50℃; for 15h;Inert atmosphere; To a 100-mL two-neck eggplant-shaped flask, 2,4- bis (trifluoromethyl) phenol (230 mg, 1 mmol, 1 eq) , potassium carbonate (346 mg, 2.5 mmol, 2.5 eq, baked at 300°C for 2 to 3 h) , and 3 mL of dry dimethylformamide were added. Then, 2 mL of dry dimethylformamide of the compound D-I (418 mg, 1.2 mmol, 1.2 eq) was gradually added thereto in an argon atmosphere. The mixture was stirred at room temperature for 2 hours and at 50°C for 13 hours. The reaction was followed by TLC (Sitheta2/EtOAc : Hexane = 1 : 1) and completed when the production of the compound of interest (Rf value: 0.4) and the exhaustion of the raw materials (phenol, Rf value: 0.9) were confirmed. The solvents were distilled off under reduced pressure using a vacuum pump. After the addition of ethyl acetate (approximately 300 mL) , the organic phase was washed with an aqueous saturated citric acid solution (100 mL, three times) and with a saturated saline (100 mL, twice) . The organic phase was dried over anhydrous magnesium sulfate. Insoluble matter was filtered off. Then, the solvents were distilled off under reduced pressure. The residue was vacuum-dried to obtain a white solid. The solid was purified by column chromatography (SiO2/ (second) EtOAc :Hexane = 1 : 1 - 4 : 1) . The solvents were distilled off under reduced pressure. The residue was vacuum- dried to obtain a pale yellow oil. Identification was conducted by 1H-NMR.Experimental Results>Pale Yellow OilYield: 252 mg (63percent)
