The condensation of a methyl group at the 6- or 8-position on the 9H-purine ring with benzaldehyde and ethyl benzoate in the presence of sodium hydride occurred to give the styryl- (4a, b) and phenacyl-9H-purines (5a, b and 6a,b). Conversion of the methyl

Coupling of 6- and 2-halo-9-phenyl-9H-purines (1, 2, and 5) with terminal acetylenes in dimethylformamide (DMF) was well catalyzed by bis(triphenylphosphino)palladium chloride to give the corresponding alkynyl-9-phenyl-9H-purines (3 and 4).
