Versuchsvorschrift

To a mixture of 5'-mesyl-d4T (6, 0.4 g) in 6 ml of DMF was added powdered sodium benzoate (0.24 g). The reaction was stirred at 100° C. for 6 hours. After cooling, water (30 ml) was added. The resulting precipitate was filtered, washed with 2×5 ml water and dried to give 5'-benzoly-d4T (7'), 0.04 g (91%).
