Procedure

A suspension of (R)-1-(5-acetoxyhexyl)-8-cyano-7-ethoxymethyl-3-methylxanthine (750 mg, 1.92 mmol) and 10% palladium on carbon (250 mg) in glacial acetic acid (40 ml) was treated with hydrogen gas (80 psi) on a Parr shaker for 3 hours. The mixture was filter through a pad of celite and then the filtrate was concentrated under reduced pressure to provide the acetic acid salt of (R)-1-(5-Acetoxyhexyl)-8-aminomethyl-7-ethoxymethyl-3-methylxanthine (800 mg, 91% yield) as a pale yellow oil.
