Reaction Steps

2.1 grams of 5,6-diamino-1,3-diethyluracil were stirred in 3.4 grams glycolic acid for 1 hour at 100° C. A 1:1 solution of ethanol and water (20 ml) was thereafter added to the cooled and stirred mixture, followed by the addition of 8 grams of sodium hydroxide in 30 ml water, which raised the pH to above 12. The solution was then refluxed for 2.5 hours, cooled, 30 ml acetic acid were added, and the mixture was then cooled overnight at 4° C. The resulting precipitate was collected and dried, to give 1,3-diethyl-8-hydroxymethylxanthine (1.5 gram).
