Abstract
PURPOSE: To obtain an oxohexylxanthine, which is a vasolidator with low toxicity, economically, by reacting an easily available inexpensive allylxanthine with acetone in the presence of a radical initiator.
CONSTITUTION: One mole of an allylxanthine of formula I: (R is lower allyl group), obtained by reacting alkyl chloride with a 3-methyl-7-lower alkylxanthine, is reacted with 1 or more moles of acetone in the presence of 0.001W2 moles of a radical initiator (an organic or inorganic peroxide) at 100W260°C, preferably 130W 220°C, under pressure to give an oxohexylxanthine of formula II.
