The first solid-phase methodology for the preparation of pyrrolo[3,2-d]pyrimidines is presented. Merrifield resin bearing a cysteamine "traceless" linker was treated with 4-oxo-N-(PhF)proline benzyl ester (10; PhF = 9-(9-phenylfluorenyl)) to provide resin-bound aminopyrrole 20, which was treated with ethyl, phenyl, 4-phenoxyphenyl
