실험 절차

To a suspension of sodium theobromine (6.00 g, 30.0 mmol) in dimethylsulfoxide (60 mL) was added 12-methanesulfonyl-1-dodecene and the reaction stirred for 16 hours at 60° C. The mixture was then poured into water (120 mL) and extracted with diethyl ether (2×100 mL). The organic portions were combined, dried using magnesium sulfate and evaporated to give a cream solid. Recrystallization from ethyl acetate/hexane 1:1 yields 6.97 g (67% yield) 1-(11-dodecenyl)-3,7-dimethylxanthine (inventive compound no. 2516) as a white solid.
