containing sodium hydride gave the corresponding 7,7′-(α,ω-alkanediyl)bis[theophylline], 1,1′-(α,ω-alkanediyl)bis[theobromine], and 1,1′-(α,ω-alkanediyl)bis[3-methyluracil]. The interaction of the theophylline, theobromine, and 3-methyluracil rings of these compounds was studied based on their 1H NMR spectra, and stacking of the two purine rings of 7,7′-(α,ω-alkanediyl)bis[theophylline] was observed.
