Procedure

In analogy to example 13, step 2, (4-bromo-thiophen-2-ylmethyl)-isobutyl-amine was reacted with 2-chlorobenzenesulfonylchloride in presence of N,N-diisopropyl ethyl amine in dichloromethane to give N-(4-bromo-thiophen-2-ylmethyl)-2-chloro-N-isobutyl-benzenesulfonamide as a colorless oil.
