Procedure

In analogy to example 1, step 2, 3-chloro-N-[5-(3-methanesulfonyl-phenyl)-thiophen-2-ylmethyl]-benzenesulfonamide (example 7, step 2) was reacted with sodium hydride in N,N-dimethylacetamide at 0° C. followed by reaction with 1-bromo-2-methylpropane at r.t. overnight to give 3-chloro-N-isobutyl-N-[5-(3-methanesulfonyl-phenyl)-thiophen-2-ylmethyl]-benzenesulfonamide as a colorless solid. MS: 515.3 ([M+NH4]+)
