Reaction Steps

To prepare N6 -cyclopenyl-9-methyl Adenine the following additional steps were taken. A mixture of 6-chloro-9-methyl Adenine (0.82 g) , cyclopentylamine (0.52 ml) , trimethylamine (0.53 ml) and ethanol. (60 ml), was refluxed for 24 hours. The solution was concentrated in vacuo to a yellow syrup. The syrup was passed through a C-18 column to give 0.78 g or 74% yield of with m.p. 108°-109° C. 1HNMR(Me2SO-d6): δ1-2 (m, 9 H); 3.7 (S, CH3); 7.6(d,NH); 8.1(S,1H); 8.2(S,1H).
