Reaction Steps

A solution of 8-chloro-7-(2-propen-1-yl)-3,7-dihydro-1H-purine-2,6-dione (1.5 g, 6.6 mmol) in DMF (40 ml) was treated with sodium carbonate (0.9 g, 8.5 mmol) and 1-bromo-3-methylbutane (1.04 g, 6.9 mmol). The stirred mixture was heated at 50° C. for 18 hours then cooled and evaporated to dryness. The residue was treated with water (60 ml) and extracted with ethyl acetate (3×80 ml). The organic fractions were combined, dried over magnesium sulfate, filtered and evaporated. The residue was triturated with a mixture of diethyl ether and cyclohexane to reveal the product as a white solid which was filtered off and dried. This gave the title compound as a white solid m/z 297[MH+].
