2-Mercaptoadenosine (I) was S-alkylated with 1-chloro-3,3,3-trifluoropropane (II) in the presence of NaH to give trifluoropropyl sulfide (III). Subsequent acetylation of (III) with Ac2O at 80 C provided (IV), which was N-alkylated with methylthioethyl iodide (V) and NaH yielding (VI). Further hydrolysis of the resulting (VI) with 0.1 M NaOH in refluxing MeOH furnished adenosine derivative (VII). The 5'-hydroxyl group of (VII) was then phosphorylated by reaction with phosphoryl chloride in cold triethyl phosphate followed by aqueous work-up. The resulting 5'-monophosphate (VIII) was treated with carbonyl diimidazole and tri-n-butylamine to produce the phosphoryl imidazole intermediate (IX), which was finally condensed with dichloromethylenebis(phosphonic acid) (X). The target compound was isolated as the tetrasodium salt upon treatment with NaI in methanol-acetone.
