Triethylamine → N-[3-((S)-1-Benzyl-pyrrolidin-3-yl)-phenyl]-3-trifluoromethoxy-benzene sulfonamide

Participants

Reaction Steps

(S)-1-Benzyl-3-(3-amino-phenyl)-pyrrolidine (0.4 g, 1.59 mmol) and commercially available 3-trifluoromethoxy-benzene sulfonylchloride (0.39 g, 1.5 mmol) were dissolved in 30 ml tetrahydrofurane. 0.66 ml of triethylamine (3.75 mmol) were added and the mixture was stirred for 16 h at room temperature. The solvent was evaporated under reduced pressure and the residue was treated with water/diethylether. After adjusting the aqueous phase to alkaline pH with 1 N aqueous NaOH, the aqueous layer was extracted with diethylether and the combined organic layers dried over magnesium sulfate, filtered and evaporated. The product was purified via silica gel chromatography using an Isco Companion semi-automated chromatography system to yield 0.512 g of the desired compound.
