Tetrabutylammonium Fluoride → 1-[2-(4-Ethynyl-phenoxy)-ethyl]-pyrrolidine

Participants

Reaction Steps

Under a nitrogen atmosphere a solution of 12.8 g (44.5 mmol) 1-[2-(4-trimethylsilanylethynyl-phenoxy)-ethyl]-pyrrolidine in 200 mL THF is combined with 15.5 g (49.0 mmol) TBAF and stirred for 3 h at RT. The solvent is distilled off i.vac., the residue taken up in EtOAc, the organic phase is washed with saturated, aqueous NaCl solution and dried over Na2SO4. After the desiccant and solvent have been eliminated the product is further reacted without any purification.
