Versuchsvorschrift

To a cooled solution of 1.83 g (9.6 mmoles) 4-toluenesulfonyl chloride in 10 mL pyridine at +10° C. was added 3.40 g (8 mmoles) of 1-(4-toluenesulfonyl)-2-hydroxymethyl-4-(4-toluenesulfonyloxy)-pyrrolidine and the mixture was stirred 18 hours. The solution obtained was then poured into 50 mL ice-cooled 2N hydrochloric acid. The precipitate was filtered, washed with water and ether. The crystalline product was purified in boiling water and ether. The crystalline product was purified in boiling ethanol to give 3.94 g of titled compound. MP 153° C. [α]D =+46.7° (c=1.9,acetone)
