الإجراء التجريبي

A mixture of 5.65 g of 3-chloro-2(R)-hydroxy-propyl(cyclohexylmethyl)phosphinic acid ethyl ester, 2.92 g of N-[1-(3-cyanophenyl)ethyl]amine, 2.60 g of Hunig base and 10 ml of ethanol is heated under reflux for 5 days, then cooled to room temperature and concentrated by evaporation. Chromatography of the residue on silica gel gives 3-{N-[1 -(3cyanophenyl)ethyl]amino}-2(S)-hydroxy-propyl(cyclohexylmethyl)phosphinic acid ethyl ester in the form of an oil; [α}20D =+8.6 0.8 (c=1.225 in trichloromethane).
