Reaction of 6-cyanopurines with excess dimethylamine and excess piperidine at room temperature or by reflux-respectively-yielded a mixture of 6-purinecarboximidamides and N,N-dialkylpurines or piperidin-1-yl(purin-6-yl)methanimine and (piperidin-1-yl)-9H-purine, respectively. 6-Purinecarboximidamides were initially formed from the reaction, whereas N,N-dialkylpurines were detected in the mixture 30 min afterward. Both purines appeared to be generated from different mechanistic pathways.
