Reaktionsschritte
In analogy to example 1, step 3, N-(4-bromo-thiophen-2-ylmethyl)-2-chloro-N-isobutyl-benzenesulfonamide (example 14, step 2) was reacted with 3-tert-butylsulfamoyl-benzeneboronic acid (CAS [221290-14-8]), Na2CO3 and dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium dichloromethane adduct in dioxane/water to give 2-chloro-N-isobutyl-N-[4-(3-tert-butylaminosulfonyl-phenyl)-thiophen-2-ylmethyl]-benzenesulfonamide as an off-white solid. MS: 553.6 ([M−H]−)
