Reaction Steps
1 g Ethyl 2-(4-chloro-3-hydroxybutanamido)acetate is dissolved in 10 ml CH2Cl2. 100 mg pyridine p-toluenesulphonate and 0.5 ml dihydropyran are added. The mixture is stirred for 7 h. The solvent is evaporated and the residue chromatographed, eluting with ethyl acetate. A colourless oil is obtained, Rf 0.5 (silica gel plates, thickness 0.25 mm, eluent ethyl acetate).
