反応手順
28.7 g (0.11 mol) of 7-ethoxymethyl-1-ethyl-3-methylxanthine were stirred at 60° C. for 60 hours in a solution of 200 ml of 5N hydrochloric acid and 200 ml of ethanol. The reaction mixture was concentrated to dryness and the residue which remained was crystallized in ethyl acetate/diisopropyl ether.
