Procedure:
A solution of (3R)-(-)-3-(3-bromophenyl)-3-(7-benzyloxyindol-1-yl) propan-1-ol (5.10 g, 11.62 mmol) and 2,6-lutidine (1.24 g, 11.62 mmol) in dry dichloromethane (20.0 ml) was added dropwise to a magnetically stirred solution of trifluoromethanesulfonic anhydride (2.20 ml, 13.10 mmol) in dichloromethane (40.0 ml) at -10° C. under nitrogen over a 25 min. period. The resulting grey solution was stirred below -10° C. for 20 min., quenched with water (250 ml), extracted into dichloromethane (2×200 ml), the combined organic extracts were washed with water (200 ml), dried (Na2SO4) and the solvent removed in vacuo at room temperature to give an orange/brown oil which was dissolved in dry tetrahydrofuran (40.0 ml) and added dropwise to the stirred lithio acetonitrile reagent(52.19 mmol) in tetrahydrofuran at -70° C. TLC inspection immediately after the addition showed that the reaction was complete. Quenched with water (20.0 ml), diluted with ethyl acetate (300 ml), washed with brine (2×200 ml), dried (Na2SO4) and adsorbed onto silica (ca. 12.0 g). Column chromatography (ethyl acetate--light petroleum (b.p. 40°-60° C.), 1:4) gave the title compound as a pale yellow oil (4.17 g, 78%). (Found: C, 67.62; H, 5.04; N, 5.94; Br, 17.60.
