Reaction Steps

(S)-2-Acetoxy-4-hydroxybutanoic acid ethyl ester (0.5 g, 2.6 mmol) in pyridine (1 ml) was added to a solution of (4-methylphenyl)sulphonyl chloride (0.53 g, 2.76 mmol) in pyridine (1 ml) at 5°. After 16 h at 5° ethyl acetate and water were added, the organic layer was separated, washed with hydrochloric acid (2N), dried (MgSO4) and the solvent evaporated to give the sub-title ester (0.8 g).
