Reaktionsschritte
640.6 g (5 mols) of 5,5-dimethylhydantoin, 420.9 g (5 mols+10% excess) of allyl chloride, 380.1 g (2.5 mols+10% excess) of potassium carbonate and 1,000 ml of dimethylformamide are reacted, and worked up, analogously to Example 1. 820 g (97.5% of theory) of a brownish waxy crude product are obtained and are purified by distillation. 713.7 g (84.9% of theory) of a distillate are obtained; this boils at 114° C./13.3 Pas and melts at 66.2°-68.7° C.
