실험 절차

A solution of (S)-1-(5-acetoxyhexyl)-7-benzyl-3-methylxanthine (350 mg) in methanol (10 ml) was treated with 1 M hydrogen chloride in ether (5 ml). After stirring at room temperature for 12 hours, the solvent was evaporated under reduced pressure. The residue was dissolved in dichloromethane (100 ml). The solution was washed with saturated aqueous sodium bicarbonate solution (30 ml), dried over anhydrous magnesium sulfate and concentrated under reduced pressure to give (S)-1-(5-hydroxyhexyl)-7-benzyl-3-methylxanthine (270 mg).
