N,N-Dialkyladeninederivatives were prepared by two different reaction sequences starting from 5-amino-4-cyanoformimidoylimidazoles. When these imidazoles were treated with dimethylformamide diethyl acetal, a 5-aminomethyleneamino-4-cyanoformimidoylimidazole was isolated and evolved to the N,N-dialkyladenine in the presence of a secondary alkylamine. The same purine structure was isolated when the
