Reaktionsschritte

Prepared by reacting 25.5 g (0.101 Mol) of 5,5-diphenylhydantoin with 21.15 g (0.108 Mol) of 3-(bromomethyl)-benzonitrile in the presence of 12.0 g (0.107 Mol) of potassium tert.-butoxide and 200 ml of anhydrous dimethylformamide. After conventional working up 34.0 g (92% of theory) of colourless crystals were obtained, mp. 160°-164° C.
