Versuchsvorschrift
In a manner analogous to the method described in example 3, rac-(4S*,5R*)-2-[4-chloro-2-ethoxy-5-(pyrrolidine-1-sulfonyl)phenyl]-4,5-bis-(4-chlorophenyl)-4,5-dimethyl-4,5-dihydro-1H-imidazole (example 53) was reacted with phosgene in the presence of triethylamine to give the title compound.
