Versuchsvorschrift
(Example 4): 1'-(3,4-dichlorobenzyl)-7'-trifluoromethyl-spiro[imidazolidine-4,3'-indoline]-2,2',5-trione, as a solid m.p. 170°-171° C., starting from 1-(3,4-dichlorobenzyl)-7-trifluoromethylindoline-2,3-dione (itself obtained as a syrup of satisfactory purity by NMR, by reaction of 3,4-dichlorobenzyl chloride with 7-trifluoromethylindoline-2,3-dione in an analogous manner to that described for the starting material in Example 1);
