实验步骤: 2.2 gm of lithium aluminum hydride was suspended in 110 ml of dried THF and stirred for 1 hour at room temperature. To the suspension was slowly added over 15 minutes a solution of 5 gm of the compound prepared in (2) above in 50 ml of THF. The mixture was stirred for 12 hours at room temperature, and after the addition of 20 ml of ethyl acetate, for a further 3 hours. Then, 5 ml of saturated aqueous solution of ammonium chloride was added to the mixture, followed by further stirring for 30 minutes. After removing the precipitate by filtration, the filtrate was washed with water and then with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated to obtain 4.27 gm of the title compound. The mixture was stirred for 12 hours at room temperature for a further 3 hours by further stirring for 30 minutes After removing the precipitate by filtration the filtrate was washed with water with saturated brine, and dried over anhydrous sodium sulfate The solvent was evaporated

实验步骤: Compound 22-1 (8.68 g) was dissolved in diethyl ether (100 ml), phosphorus tribromide (6.35 ml) was added under ice-cooling, and the mixture was stirred under ice-cooling for 3 hr. To the reaction mixture was slowly added water was added, and the mixture was extracted with diethyl ether. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to give the object product (5.00 g) as a yellow oil. cooling cooling for 3 hr was added the mixture was extracted with diethyl ether The organic layer was washed with saturated brine dried over anhydrous magnesium sulfate The solvent was evaporated under reduced pressure
