Versuchsvorschrift

A reaction mixture of 44 g (0.2 mol) 4-iodophenol, 34 g (0.2 mol) 1-(2-chloro-ethyl)-pyrrolidine-hydrochloride, 110.56 g (0.8 mol) K2CO3 and 800 mL DMF is stirred for 48 h at RT. The reaction mixture is filtered and the filtrate is evaporated down. The residue is taken up in water and extracted with EtOAc. The organic phase is extracted with saturated NaCl solution and dried over Na2SO4. The purification is carried out by column chromatography on silica gel (EtOAc/MeOH/NH3 85:15:1.5).
