2', 3'-O-Isopropylidene-5'-O-benzoylinosine and 2', 3', 5'-tri-O-benzoylinosine were reacted with N, N-dimethylformamide-thionyl chloride complex in chloroform solution. Resulting 6-chloro compound was further reacted with morpholine, dimethylamine and thiourea to afford 6-morpholino-, 6-dimethylamino-and 6-mercapto-derivative of 9-β-D-ribofuranosylpurine in a good overall yield.
