反应详情

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.
