as well as glutathione-containing water, and their instability was closely related to their HCV inhibitory activity. A preliminary study of the mechanism of action showed that the sulfonamide bond at the 9-position of purine would be the primary degradation site and the resulting sulfonylation degradation species would mediate the anti-HCV activity of 9-sulfonyl-9(H)-purines. Results of this study demonstrated

effective for a wide variety of aryl bromide coupling partners, is predicated upon a halogen atom abstraction/nickel radical-capture mechanism that is generically successful across an extensive range of carbonyl substrates. The construction and use of arylacetic acid products have further enabled two-step protocols for the delivery of valuable building blocks for medicinal chemistry, such as aryldifluoromethyl
The synthesis of novel 6-chloro/morpholino/amino/-9-sulfonylpurine derivatives was accomplished in two ways, either (i) involving the condensation reaction of 6-chloropurine with commercially available arylsulfonyl chlorides in acetone and the presence of aqueous KOH at 0 °C, followed by the substitution of C6-chlorine with morpholine, or (ii) employing a reversed synthetic approach where 6-morpholinopurine
