실험 절차

5,530 mg of sodium hydride are added to a solution of 7.46 g of 3-{3-[4-acetyl-3-hydroxy-2-(3,3,3-trifluoropropyl)-phenoxy]-propoxy}-nitrobenzene in 75 ml of dimethylformamide and the reaction mixture is warmed to 40°. 5.7 g of methyl iodide are added dropwise in the course of 15 minutes. Thereafter, the reaction mixture is kept at 40° C. for a further hour. After cooling, it is poured onto dilute hydrochloric acid and extracted with methylene chloride and the extract is evaporated. Recrystallisation from ether/hexane gives 3-{3-[4-acetyl-3-methoxy-2-(3,3,3-trifluoropropyl)-phenoxy]-propoxy}-nitrobenzene.
