实验步骤: 1.0 g 4-Hydroxy-3-methoxybenzonitrile, 1.1 g potassium carbonate and 2.0 g 4-(iodomethyl)-tetrahydropyran were placed in 20 mL acetone and heated to reflux overnight. After this time, 1.1 g potassium carbonate was added and the reaction was heated at reflux for a further 2 h before more 0.93 g potassium carbonate was introduced and reflux was continued for a further 3 h. The mixture was then cooled to ambient temperature and concentrated under reduced pressure. The material that remained was partitioned between diethyl ether and water and the aqueous phase was removed and extracted with additional diethyl ether. The combined organic fractions were dried, filtered and the filtrate was concentrated under reduced pressure. Purification by silica gel chromatography (SiO2: ethyl acetate/heptanes: 10% to 30%) provided the title compound. heated to reflux overnight the reaction was heated was introduced reflux concentrated under reduced pressure The material that remained was partitioned between diethyl ether and water the aqueous phase was removed extracted with additional diethyl ether The combined organic fractions were dried filtered the filtrate was concentrated under reduced pressure Purification by silica gel chromatography (SiO2: ethyl acetate/heptanes: 10% to 30%)
