A solution of 31 g of 1,3-dimethyl-7-(5-hexenyl)xanthine and 34.9 g of m-chloroperbenzoic acid (70% pure) in 700 ml of chloroform was stirred at room temperature for 48 hours. The mixture was shaken with 10% strength sodium dithionite solution until the test with starch-iodide paper was negative, and washed with sodium bicarbonate solution and then with water to neutrality, dried and evaporated under reduced pressure.
