Reaction Steps

100 mg of 4-chloro-N-(1,2-diphenyl-1H-benzimidazol-5-yl)benzenesulfonamide was suspended in 0.5 ml of N,N-dimethylformamide, mixed with 6 mg of sodium hydride and stirred for 30 minutes at 20° C. 56 mg of 4-bromobutyric acid methyl ester was added, it was allowed to stir for 15 hours, mixed with water, extracted three times with ethyl acetate, the extracts were dried on sodium sulfate, concentrated by evaporation in a vacuum, and the residue was digested with diisopropyl ether.
