Reaction Steps
Compound 146.2 was prepared as described for example 1.2, by reacting compound 1.1, instead of with 2-bromobenzyl bromide, with 3-bromo-4-bromomethyl-N,N-dimethylbenzenesulfonamide (146.3, prepared by reacting 3-bromo-4,N,N-trimethylbenzenesulfonamide with N-bromosuccinimide and N,N′-azobis(2-methylpropionitrile) in tetrachloromethane). 3-Bromo-4-[3-(4-cyano-3-trifluoromethylphenyl)-5,5-dimethyl-2,4-dioxoimidazolidin-1-ylmethyl]-N,N-dimethylbenzenesulfonamide was obtained. (Molecular weight 572.03 (C22H20BrF3N4O4S); retention time Rt=2.38 min. [B]; MS (ESI): 573.25 (MH+).
