Reaction Steps

4-[4′-(4-(2,4-Dichloro-phenyl)-1-{4-[1,1,4-trioxo-5-(2-trimethylsilanyl-ethoxy methyl)-[1,2,5]thiadiazolidin-2-yl]-phenyl}-1H-imidazol-2-ylmethyl)-biphenyl-4-yl]-piperazin-2-one (17 mg, 0.02 mmol) was treated as described in general procedure L (using iodomethane) and general procedure W stepwise to give the desired compound 4-(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)-1-methyl-piperazin-2-one.
