Procedure

To a solution of 1.2 g of isobutyl P-[3-azido-2(S)-hydroxy-propyl]-P-methyl-phosphinate in 25 ml of ethanol are added 0.25 g of 5% palladium on charcoal. The resulting mixture is hydrogenated at 1 bar until hydrogen uptake ceases. The mixture is then filtered and the filtrate evaporated to give isobutyl P-[3-amino-2(S)-hydroxy-propyl]-P-(methyl)-phosphinate as a viscous oil, 31P-NMR spectrum: δ=+55.6 and +54.6 ppm (CDCl3), [α]D25 =+10.9 (c=0.50% in ethanol).
