Procedure

5-{4-[2-(4′-Amino-biphenyl-4-ylmethyl)-4-(2,4-dichloro-phenyl)-imidazol-1-yl]-phenyl}-1,1-dioxo-2-(2-trimethylsilanyl-ethoxymethyl)-[1,2,5]thiadiazolidin-3-one (74 mg, 0.1 mmol) was treated as described in general procedure U using 5-bromovaleryl chloride (40 mg, 0.2 mmol) to give the intermediate 5-bromo-pentanoic acid [4′-(4-(2,4-dichloro-phenyl)-1-{4-[1,1,4-trioxo-5-(2-trimethylsilanyl-ethoxymethyl)-[1,2,5]thiadiazolidin-2-yl]-phenyl}-1H-imidazol-2-ylmethyl)-biphenyl-4-yl]-amide, which was treated with 1,8-diazabicyclo[5,4,0]undec-7-ene (46 mg, 0.3 mmol) at 0° C. in 1 mL anhydrous DMF (stirring at room temperature under nitrogen over night), followed by regular ethyl acetate/water workup and silica gel column chromatography to give 1-[4′-(4-(2,4-dichloro-phenyl)-1-{4-[1,1,4-trioxo-5-(2-trimethylsilanyl-ethoxymethyl)-[1,2,5]thiadiazolidin-2-yl]-phenyl}-1H-imidazol-2-ylmethyl)-biphenyl-4-yl]-piperidin-2-one, which was finally treated as described in general procedure W to give the desired compound 1-(4′-{4-(2,4-dichloro-phenyl)-1-[4-(1,1,4-trioxo-[1,2,5]thiadiazolidin-2-yl)-phenyl]-1H-imidazol-2-ylmethyl}-biphenyl-4-yl)-piperidin-2-one.
