反応手順

10 g. triacetyl-6-chloro-9-(β-D-ribofuranosyl)-purine and 10 g. allyl-cyclohexylamine were heated under reflux for 1 hour in 100 ml. butanol. The butanol was then distilled off in a vacuum, the residue was dissolved in chloroform and the chloroform solution was then shaken out successively with dilute hydrochloric acid, dilute aqueous sodium bicarbonate solution and water. The chloroform solution was then dried over anhydrous sodium sulfate and evaporated to a syrup. This was dissolved in methanol and the solution, after the addition of 5 ml. 1N sodium methylate solution was heated for 10 minutes on a steambath. After cooling, the solution was distilled off to dryness, the residue was dissolved in chloroform and the chloroform solution was washed with water. The organic phase was dried and evaporated and the residue obtained recrystallized from ethanol. 6.1 g. (59% of theory) N(6)-allyl-N(6)-cyclohexyl-adenosine were obtained; m.p. 123° - 125° C.
