Versuchsvorschrift
2-(4′-tert-Butyl-biphenyl-4-ylmethyl)-4-(2,4-dichloro-phenyl)-1-(4-iodo-phenyl)-1H-imidazole (191 mg, 0.3 mmol) was treated as described in general procedure R using L-2-aminobutyric acid (310 mg, 3 mmol) to give (S)-2-{4-[2-(4′-tert-butyl-biphenyl-4-ylmethyl)-4-(2,4-dichloro-phenyl)-imidazol-1-yl]-phenylamino}-butyric acid, which was then treated as described in general procedure F to give (4S)-5-{4-[2-(4′-tert-butyl-biphenyl-4-ylmethyl)-4-(2,4-dichloro-phenyl)-imidazol-1-yl]-phenyl}-4-ethyl-1,2,5-thiadiazolidine-3-one-1,1-dioxide.
