Procedure

A mixture of 1-bromo-4-iodo-benzene (50.0 g, 177 mmol), (S)-pyrrolidin-3-ol (28.6 mL, 353 mmol), CuI (6.73 g, 35.3 mmol) and K3PO4.H2O (81.4 g, 353 mmol) in N,N-dimethylaminoethanol (177 mL) was stirred at 55° C. for 60 h. The mixture was allowed to cool to rt, and water was added. The mixture was extracted several times with CH2Cl2. The combined org. extracts were washed with a 1:1 mixture of aq. conc. NH3 and water. The NH3-containing aq. layer was extracted with CH2Cl2. The combined org. extracts were dried over MgSO4, filtered, and the solvents were removed under reduced pressure. Crystallization of the crude from EtOAc/heptane yielded the title compound (36.1 g, 84%).
