실험 절차

A mixture of 3.79 g of anhydrous triethylamine and 4.5 g ethyl n-butylphosphinate in 100 ml of anhydrous tetrahydrofuran under an inert atmosphere is treated with 4.07 g of trimethylchlorosilane. The resulting suspension is stirred for 20 hours at room temperature and the solid removed by filtration. Concentration in vacuo affords a cloudy, colourless oil which is treated with 6.09 g of anhydrous N-(2,3-epoxypropyl)phthalimide and 0.5 g of anhydrous zinc chloride. The mixture is heated to 66° C. under an inert atmosphere for 3 hours, cooled to 20° and diluted with dichloromethane. The organic solution is washed with 100 ml 10% of aqueous sodium bicarbonate solution and dried over anhydrous magnesium sulphate. Removal of the solvent and chromatography on silica gel affords ethyl 3-phthalimido-2-trimethylsilyloxy-propyl(n-butyl)phosphinate as a viscous oil.
