Reaction Steps

A material of 283 mg of 3-(N-tert.-butyloxycarbonylamino)-2-(4-chlorophenyl)-propionaldehyde, 150 mg of ethyl n-butyl-phosphinate and 101 mg of triethylamine is heated to 100° C. for 21/2 hours. The mixture is cooled to room temperature and the volatile components are removed in high vacuum. Chromatography of the residue on silica-gel affords ethyl 3-(N-tert.-butyloxycarbonylamino)-2-(4-chlorophenyl)-1-hydroxy-propyl-(n-butyl)phosphinate.
