Procedure
(1S)-(−)-1-(4-Bromophenyl)ethylamine (2.4 g), 2,2′-dibromodiethylether (3.25 g) and N,N-diisopropylethylamine (6 ml) were heated to 100° C. in dimethylformamide (40 ml) for 18 h, allowed to cool and partitioned between water and ethyl acetate. The organic phase was dried (MgSO4), evaporated under vacuum and purified by column chromatography using a 0-40% ethyl acetate/iso-hexane gradient. The product was obtained as a yellow oil (1.91 g).
