Procedure

To a solution of (2R)-3-(4-morpholinyl)-1,2-propanediol (0.447 g, 2.77 mmol) in CH2Cl2 (7.5 mL) was cooled to 0° C. and added thionyl chloride (0.41 mL, 5.55 mmol, 2.0 equiv.) was added dropwise. The resulting solution was heated at the reflux temperature for 1 hr, cooled to room temperature and concentrated under reduced pressure to give 4-[(4R)-(2-oxido-1,3,2-dioxathiolan-4-yl)methyl]morpholine hydrochloride (0.70 g, 104%). This material was used in the next step without further purification.
