実験手順
To a solution of (S)-9-[2-(diethoxyphosphorylmethoxy)-3-hydroxypropoxy]adenine (0.09 g, 0.24 mmol) in dry dichloromethane (3 ml) was added trimethylsilyl bromide (0.31 ml, 2.4 mmol) and the solution stirred at ambient temperature for 4 hours. The solvent was removed under reduced pressure and the residue co-evaporated with acetone/water 1:1 (x3). Crystallisation of the residue from water/acetone gave the title compound as a white solid (0.06 g, 78%), mp. 93°-198° C.
