Reaction Steps

To a solution of 3.86 g (19 mmol) of 4-bromothioanisole in 90 mL of Et2O cooled at -78° C., was added 22 mL of 1.7M solution of t-BuLi in pentane (38 mmol) dropwise. The reaction mixture was stirred for 15 min at -78° C. and a solution of 2.23 g of 2-(4-Fluorophenyl)-2-cyclopenten-1-one in 10 mL of Et2O was added. After stirring for 15 min at -78° C., the reaction mixture was warmed to 0° C., and quenched with 50 mL of sat. NH4Cl. The product was extracted with 100 mL EtOAc, dried over Na2SO4, and purified by flash chromatography, eluted with 4:1 hexane/EtOAc to give 3.4 g of the desired product. 1H NMR (CDCl3) δ2.12 (1H, s), 2.34 (2H, m), 2.44 (3H, s), 2.45-2.52 (1H, m), 2.56-2.65 (1H, m), 6.37 (1H, m), 6.84 (2H, J=8.7 Hz, t), 7.17 (2H, J=8.3 Hz, d), 7.24-7.33 (4H, m).
