الإجراء التجريبي

To a mixture of hydroxymethyl phosphonic acid diethylester (1.68 g, 10 mmol), Z-1,4-dichloro-2-butene (1.9 g, 15 mmol) and tetra-n-butylammonium iodide (0.36 g, 1 mmol) in anhydrous tetrahydrofuran (15 ml), sodium hydride (0.48 g, 12 mmol, 60% in oil) is added at 0° C. The resulting mixture is stirred overnight at 20° C., hydrolyzed with a saturated solution of ammonium chloride and extracted with diethylether. The title product is obtained by flash chromatography on silica gel (1.2 g, 45%).
