Treatment of 2-amino-6-chloro-9-beta-D-ribofuranosylpurine (I) with acetoxyisobutyryl bromide (II) led to a mixture of acetoxy bromo derivatives (III) and (IV) which, upon reductive treatment with activated zinc, furnished the 2',3'-dehydro compound (V). Deprotection of (V) with K2CO3 in aqueous methanol provided the free nucleoside (VI). Finally, nucleophilic displacement of the chlorine of (VI) with cyclopropylamine (VII) afforded the target compound.
