Reaction Conditions

Reaction Steps

0.4 g of 3-Bromo-N-[4-((S)-1-propyl-pyrrolidin-3-yl)-phenyl]-benzenesulfonamide (0.94 mmol), 0.156 ml pyrrolidin (1.89 mmol), 160 mg sodium tert-butanolate ((1.66 mmol) and 540 mg sodium sulfate were dissolved in 15 ml of tetrahydrofuran and heated to 50° C. 120 mg of 2,2′-bis(diphenylphosphino)-1,1′-binaphthalene (0.19 mmol) and 85 mg tri(dibenzylidenacetone)dipalladium(0) (0.09 mmol) were added and the reaction stirred for 4 h under reflux. After workup, the partially converted starting material was reacted again under the same reaction conditions until completion. The solvents were evaporated under reduced pressure, the residue was treated with dichloromethane and water, the organic layer was dried over magnesium sulfate, filtered, and the solvent was evaporated under reduced pressure. The crude product was purified with silica gel chromatography with dichloromethane/methanol (0-20%) as eluent using a semi-automated ISCO companion instrument, yielding 0.309 g of the purified product.
