反応条件: temp:0.00; pressure:0.00; stir:

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of 150 ml of diborane (1M in THF) in 250 ml of dry THF. Ten g of 1-indane carboxamide is slowly added. Reaction mixture is stirred at reflux for three hours, cooled to room temperature, and worked up by slowly adding 150 ml of 1N HCl. THF is distilled off under reduced pressure, the aqueous solution is brought to pH~13 by addition of NaOH. It is extracted with ethyl acetate (2×300 ml). The organic extract is washed with water (1×100 ml), dried over MgSO4, filtered, and evaporated to dryness affording 6.5 g (71%) of 1-indanylmethylamine. It was used as is in the next reaction. Reaction mixture at reflux for three hours THF is distilled off under reduced pressure the aqueous solution is brought to pH~13 by addition of NaOH It is extracted with ethyl acetate (2×300 ml) The organic extract is washed with water (1×100 ml) dried over MgSO4 filtered evaporated to dryness

実験手順: A mixture of 3.0 g of 6-chloropurine riboside, 2.0 g of 1-indanylmethylamine as prepared in Example A hereinafter and 3.18 g of triethylamine are refluxed in 75 ml of absolute ethanol under nitrogen for 24 hours. The reaction is cooled to room temperature, precipitated nucleoside is filtered, washed with ethanol and dried affording 2.78 g (67%) of N6 -[2,3-dihydro-1H-inden-1-yl]methyl-adenosine having a melting point of 137°-139° C. Anals. calcd. for C20H23N5O4 ; Found: C=60.44; H=5.83; N=17.62 C=60.81; H=5.70; N=17.35. precipitated nucleoside is filtered washed with ethanol dried
