Procedure
A mixture of 5.18 g of 3-(benzyloxycarbonylamino)propionaldehyde, 2.7 g of ethyl P-methylphosphinate and 2,53 g of triethylamine is heated to 100° under an inert gas atmosphere for 2 hours. After cooling to room temperature the volatile materials are removed under reduced pressure to afford a viscous oil. Chromatography thereof on silica gel gives ethyl P-(3-benzyloxycarbonylamino-1-hydroxy-propyl)-P-methyl-phosphinate as a colourless, viscous oil.
