Procedure

In analogy to example 13, step 2, isobutyl-[5-(3-methanesulfonyl-phenyl)-thiophen-2-ylmethyl]-amine (example 15, step 2) was reacted with 3-chloro-2-fluorophenylsulfonyl chloride and N,N-diisopropyl ethyl amine in dichloromethane to give 3-chloro-2-fluoro-N-isobutyl-N-[5-(3-methanesulfonyl-phenyl)-thiophen-2-ylmethyl]-benzenesulfonamide as a colorless oil. MS: 532.7 ([M+NH4]+)
