Potassium Carbonate → Ethyl(4-{4-(benzyloxy)-3-[(4-fluorophenyl)sulphonyl]benzyl}-3,5-dimethylphenoxy)acetate

Participants

Reaction Steps

85 mg (0.18 mmol) of 4-{4-(benzyloxy)-3-[(4-fluorophenyl)sulphonyl]benzyl}-3,5-dimethylphenol (Example X) are dissolved in 2 ml of dimethylformamide. 30 mg (0.21 mmol) of potassium carbonate and 33 mg (0.20 mmol) of bromoethyl acetate are added. The mixture is stirred at room temperature overnight. Saturated ammonium chloride solution is then added, and the mixture is extracted three times with diethyl ether. The combined organic phases are washed three times with water, dried with sodium sulphate and concentrated under reduced pressure. This gives 80 mg (96.5% of theory) of ethyl (4-{4-(benzyloxy)-3-[(4-fluorophenyl)sulphonyl]benzyl}-3,5-dimethylphenoxy)acetate.
