実験手順: To a stirred solution of 24.0 g (0.131 mole) of 1-chloro-5-phenylpentane (Columbia Organics, Camden, S.C.) in 150 mL of dimethylformamide was added 24.3 g (0.131 mole) of potassium phthalimide (Aldrich) and the reaction mixture was heated at reflux under a nitrogen atmosphere for 15 hr. The solvent was evaporated under reduced pressure to heave a viscous, oily residue. The residue was triturated with 200 mL of water and then the mixture was extracted with four 200-mL portions of methylene chloride. The combined methylene chloride extracts were washed with two 200 mL portions of 2N sodium hydroxide solution, twice with 200 mL portions of water and dried over magnesium sulfate. The solvent was evaporated under reduced pressure to give 35.0 g (91%) of title compound as a viscous oil. A sample of this viscous oil was further purified by high pressure liquid chromatography (Waters Associates Prep LC/System 500A, PrepPak® 500 silica gel; ethyl acetate-hexanes, 1:10). Fractions containing title compound were combined and the solvents were evaporated under reduced pressure to give purified title compound as a colorless, viscous oil. the reaction mixture was heated at reflux under a nitrogen atmosphere for 15 hr The solvent was evaporated under reduced pressure The residue was triturated with 200 mL of water the mixture was extracted with four 200-mL portions of methylene chloride The combined methylene chloride extracts were washed with two 200 mL portions of 2N sodium hydroxide solution, twice with 200 mL portions of water dried over magnesium sulfate The solvent was evaporated under reduced pressure

実験手順: Crude 5-phenylpentyl chloride (1.3 g) was added to a stirred solution of 4-mercapto-1-β-D-ribofuranosylpyrazolo [3,4-d]pyrimidine (2.0 g) and potassium bicarbonate (0.7 g) in N,N-dimethylformamide. The reaction mixture was heated on a steam bath for 25 hours. An additional 0.7 g of potassium bicarbonate was added and after heating for 1 hour more, the mixture was poured into water. The cooled aqueous mixture was extracted with chloroform. The chloroform soluble material was chromatographed on a silica gel column. The fractions containing the compound were combined and evaporated. Trituration with ether gave 0.4 g of crude product. This was dissolved in ethyl acetate and washed with water. The dried ethyl acetate solution was evaporated and purified by reversed phase chromatography in methanol water (80:20 vol/vol) to give 0.28 g of product m.p. 72°-75° C. (indefinite).
