Procedure

Ammonia gas was blown into a solution of 40 mg of 3-[[(S)-1-[[(2S,3S)-3-hexyl-4-oxo-2-oxetanyl]methyl]dodecyl]oxy]propionic acid (Example L) in 2.5 ml of acetonitrile until the solution is saturated and subsequently 50 mg of HBTU were added. Then, the mixture was filtered and evaporated and the residue was chromato- graphed on silica gel with 5 percent methanol in methylene chloride. There were obtained 32.5 mg of (3S,4S)-4-[(S)-2-(2-carbamoylethoxy)tridecyl]-3-hexyl-2-oxetanone, m.p. 35°.
