A simple three-step method for the solution-phase combinatorial synthesis of 2,6,9trisubstituted purines from 2,6-dichloropmine is described. The synthesis exploits the use of resin capture to remove excess reagent used in the f'mal step.

โฆ Synopsis
In an attempt to discover a high-throughput method for the synthesis of 2,6,9-trisubstituted purines, it was found that microwave irradiation was beneficial in accelerating the nucleophilic displacement of halogens by amines at the C-2 position of the purine nucleus. A method for microwave-assisted solid-phase synthesis (MASS) of 2,6,9-trisubstituted purines is presented.
