Versuchsvorschrift
To a solution of (R)-7-ethoxymethyl-1-(5-hydroxyhexyl)-3-methyl-8-methylsulfanylxanthine (20 mg, 0.054 mmol) in ethanol (1.9 ml) was added concentrated hydrochloric acid (0.10 ml). The reaction mixture was stirred at 80° C. for 24 hours. After evaporation of the solvent under reduced pressure, the crude product was purified by flash chromatography on silica gel eluting with ethyl acetate-methanol (7:1) to provide (R)-1-(5-hydroxyhexyl)-3-methyl-8-methylsulfanylxanthine (12 mg, 70% yield) as a white solid.
