実験手順

A suspension of 22 g (100 mmol) 4-iodophenol, 17 g (100 mmol) 1-(2-chloro-ethyl)-pyrrolidine (used as the hydrochloride) and 55.3 g (400 mmol) K2CO3 in 400 mL DMF is stirred for 48 h at RT. The solvent is evaporated down i.vac., the residue is combined with water, the aqueous phase exhaustively extracted with EtOAc, the combined organic phases are washed with saturated, aqueous NaCl solution and dried over Na2SO4. After the desiccant and solvent have been eliminated the residue is purified on silica gel (EtOAc/MeOH/NH3 85:15:1.5).
