Versuchsvorschrift

16.12 g (0.1 mol) of 1-phenylhydantoin, 12.25 g (0.1 mol+15% excess) of 2-chloroethyl vinyl ether, 7.25 g (0.05 mol+5% excess) of potassium carbonate and 50 ml of dimethylformamide are reacted for 1 hour at 120°-125° C. The reaction mixture is worked up analogously to Example 1 to 20.3 g (82.4% of theory) of a brownish, crystalline crude product melting at 119°-120° C. are obtained. 5 g of crude product are recrystallised from 25 ml of chloroform and 3.9 g of the pure compound are isolated. The melting point is 120°-121° C.
