Reaktionsschritte

To a stirred solution of 2-chloro-N-[5-(3-methanesulfonyl-phenyl)-thiophen-2-ylmethyl]-benzenesulfonamide (example 4, step 2, 60 mg) in dichloromethane (0.5 mL) were added N,N-diisopropyl ethyl amine (21 mg) and benzoyl chloride (20 mg) at 0° C. The mixture was stirred at r.t. overnight. Ice cold water was added and the mixture was extracted with ethyl acetate. The organic phase was dried (MgSO4), filtered and concentrated under reduced pressure. The product was purified by chromatography (SiO2, cyclohexane/ethyl acetate 1:0 to 0:1) to give N-benzoyl-2-chloro-N-[5-(3-methanesulfonyl-phenyl)-thiophen-2-ylmethyl]-benzenesulfonamide (76 mg) as a colorless solid. MS: 568.2 ([M+Na]+)
