Comparison of the 13C and 15N NMR spectra of 8-azatheophylline with those of its three methylated derivatives and other model compounds from the literature showed that 8-azatheophylline exists to the extent of 80percent in the N-2 tautomeric form in DMSO solution. KEY WORDS 13C NMR 15N NMR Prototropism 4,6-Dimethyl-5,7-dioxo-1,2,3-triazolo<4,5-d>pyrimidine
