Reaktionsschritte
In analogy to example 1, step 3, N-(2-bromo-thiazol-5-ylmethyl)-2-chloro-benzenesulfonamide was reacted with (3-methylsulfonylphenyl)-boronic acid, Na2CO3 and dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium dichloromethane adduct in dioxane/water to give 2-chloro-N-[2-(3-methanesulfonyl-phenyl)-thiazol-5-ylmethyl]-benzenesulfonamide as a light yellow oil. MS: 443.3 ([M+H]+)
