Reaction Conditions

Reaction Steps

To a suspension of sodium theobromine (4.05 g, 20.0 mmol) in dimethylsulfoxide (50 mL) was added 1-methanesulfonyl-4-(S)-methyl-8-methylnon-7-ene and the reaction stirred for 16 hours at 60° C. The mixture was then poured into water (100 mL) and extracted with ethyl acetate (100 mL, 2×50 mL). The organic portions were combined, dried using magnesium sulfate, and evaporated to give a residue which was purified by column chromatography (ethyl acetate/hexane) to yield 1.83 g (30% yield) 1-(4-(S)-Methyl-8-methylnon-7-enyl)-3,7-dimethylxanthine (inventive compound no. 2536S) as a white solid.
