Procedure
22 g (0.1 mol) of the xanthine from stage (a) are reacted with 16.6 g (0.11 mol) of 1-chloro-5-hydroxy-5-methylhexane (Example 1a) and 15.2 g (0.11 mol) of potassium carbonate in 500 ml of dimethylformamide under the experimental conditions described in Example 2, and the mixture is worked up. The reaction product is obtained in pure form without prior column chromatography, by recrystallization once from ethyl acetate with the addition of petroleum ether, at the boil.
