Abstract
PURPOSE: To obtain the title compound useful as a medicine having improved vasodilator action, by reacting 3,7-dimethylxanthine with 5-oxo-1-hexanol in the presence of two specific types of compounds directly.
CONSTITUTION: 3,7-Dimethylxanthine is reacted with 5-oxo-1-hexanol in the presence of triphenylphosphine and a dialkyl azodicarboxylate in an ether, e.g. THF or dioxane, at room temperature with stirring to give 1-(5-oxo-hexyl)-3,7-dimethylxanthine, e.g. the compound of the formula.
