Procedure

A mixture of 8-bromoadenosine (1 mmol), arninoethylphosphonate (2 mmol), and sodium hydroxide (2 mmol) in ethanol-water in a sealed tube was warmed at 110° C. under nitrogen. After 24 h the cooled reaction mixture was purified through preparative HPLC to give 8-(2-phosphonoethylamino)-adenosine (4.1). mp 175° C.; Anal. calcd. for C12H19N6O7P+0.5 H2O: C, 36.10; H, 5.05; N, 21.05; P, 7.76. Found: C, 36.08; H, 4.83; N, 20.36; P, 7.86.
