Versuchsvorschrift

Compound 110.2 was prepared as described for example 1.2, by reacting compound 1.1, instead of with 2-bromobenzyl bromide, with 2-bromo-1-bromomethyl-4-methoxybenzene (prepared by N-bromosuccinimide bromination from 2-bromo-4-methoxy-1-methylbenzene; 1H NMR: 7.56, d, 1H, 7.23, s, 1H, 7.0, d, 1H, 4.74, s, 2H; 3.8, s, 3H). 4-[3-(2-Bromo-4-methoxybenzyl)-4,4-dimethyl-2,5-dioxoimidazolidin-1-yl]-2-trifluoromethylbenzonitrile was obtained. (Molecular weight 495.04 (C21H17BrF3N3O3); 1H NMR: 8.38, d, 1H, 8.25, s, 1H, 8.1, d, 1H, 7.5, d, 1H, 7.22, s, 1H, 6.95, d, 1H, 4.6, s, 2H, 3.79, s, 3H, 1.4, s, 6H.
