Versuchsvorschrift
2-Furan-2-yl-5-methanesulfonyl-[1,2,4]triazolo[1,5-a][1,3,5]triazin-7-ylamine (0.7 mmol, 1 eq.; see J. Chem. Soc. Perkin Trans. 1, 801 (1995)) and 2,5-diaza-bicyclo[2.2.1]heptane (5 eq.) were suspended in 10 mL of CH3CN. The mixture was stirred under reflux for 2 hours. It was then cooled to room temperature and concentrated under reduced pressure. The residue was taken up in CH2Cl2 and washed with water, brine, dried with Na2SO4, and concentrated under reduced pressure. The resulting crude product was purified by column chromatography (95% CH2Cl2, 4% MEOH, 1% Et3N) to afford 5-(2,5-diaza-bicyclo[2.2.1]hept-2-yl)-2-furan-2-yl-[1,2,4]triazolo[1,5-a][1,3,5]triazin-7-ylamine.
