Participants

Reaction Steps

Trifluoroacetic acid (30 ml) was added to a solution of (R)-1-(5-acetoxyhexyl)-3-(N-t-butyloxycarbonyl-6-aminohexyl)-7-methylxanthine (1.37 g) in dichloromethane (30 ml). After stirring at room temperature for 1 hour, the mixture was concentrated under reduced pressure. The residue was dissolved in dichloromethane (50 ml). The solution was washed with saturated aqueous sodium bicarbonate solution (20 ml), with water (20 ml), with saturated aqueous sodium chloride solution (20 ml), dried over anhydrous magnesium sulfate and concentrated under reduced pressure to provide (R)-1-(5-acetoxyhexyl)-3-(6-aminohexyl)-7-methylxanthine (1.073 g).
