Reaktionsschritte

The experiment of Example 1 was repeated in every essential detail except for the following. The suspension was prepared using 2.0 g (6.98 mmol) of the 6-chloropurine riboside in 30 ml of absolute ethanol. 1-(2-Aminoethyl) piperidine (commercially available) was added in an amount of 1.07 g (0.7 ml, 8.3 mmol). Also added to this suspension was 1.5 ml (10.5 mmol) of triethylamine. The reaction mixture was refluxed for 72 hours. The resulting residue was chromatographed on a silica gel column eluting with an eluent of 20 parts methanol, 79 parts dichloromethane and one part ammonium hydroxide. The title product was produced in a yield of 1.1 g (42%).
