実験手順

83 g (0.5 mol) of 3-methylxanthine are dissolved in 1250 ml of dimethylformamide, and 12 g (0.5 mol) of sodium hydride are added in portions at room temperature, while stirring. Stirring is continued for 30 minutes, after which 55.3 g (0.5 mol) of 1-chloro-2,3-propanediol in 100 ml of dimethylformamide are added dropwise and the mixture is heated for 18 hours at 110° C., while stirring. Working up is carried out as described in Example 55a).
