A mixture of 15.4 g (0.1 mole) of 6-chloropurine, 75 ml of N,N-dimethyl formamide, 13.8 g (0.1 mole) of potassium carbonate and 26.8 g (0.1 mole) of 3-(4-phenoxymethylpiperidino)-propyl chloride is heated to 40° C for 6 hours, while stirring. The reaction mixture is then mixed with water extracted with ethyl acetate and the extract is dried and evaporated. The residue obtained is recrystallized from ethyl acetate/ligroin. There are obtained 16.2 g (42% of theory) of 6-chloro-9-[3-(4-phenoxymethylpiperidino)-propyl]-purine; m.p. 95° - 96° C.
