Procedure

To a solution of 10 g of adenosine in 400 ml of dimethyl formamide was added 2.25 g of 60% sodium hydride (oil). After one hour, 8.5 ml of 1-bromononane was added. The reaction was stirred for 16 hours. Ice was added and the solution evaporated in vacuo. Water and ethyl acetate were added. The organic phase was separated, dried, and evaporated in vacuo to give a white solid, which was recrystallized from ethanol to yield 4.8 g of the title compound, m.p. 143–144° C. analysis for: C19H31N5O4. Calculated: C, 57.99; H, 7.94; N, 1779. Found: C, 58.13; H, 7.93; N, 17.83.
