1,2-Dichloroethane → 4-Chloro-N-(4-pentyl-bicyclo[2.2.2]octane-1-carbonyl)-benzenesulfonamide

Participants

Reaction Steps

0.42 g of 4-chlorophenylsulfonamide, 60 mg of DMAP and 0.42 g of EDC are added to a solution of 0.5 g of 4-pentyl-bicyclo[2.2.2]octane-1-carboxylic acid in 8 ml of DMF, the mixture obtained is stirred for ca. 16 h at RT and solvent from the mixture obtained is evaporated. The evaporation residue obtained is dissolved in EtAc and washed with 1 N HCl, saturated NaHCO3 solution and brine and the organic phase obtained is dried. Solvent of the organic phase obtained is evaporated and the evaporation residue obtained is subjected to chromatography. 4-Chloro-N-(4-pentyl- bicyclo[2.2.2]octane-1-carbonyl)-benzenesulfonamide is obtained in the form of a white powder;
