Reaction Steps

A solution of 1.3M s-BuLi in cyclohexane (23.91 mL, 31.1 mmol) was added to an ether/liquid N2 cooled (-90° C.) solution of TMEDA (3.97 g, 34.2 mmol) in THF (40 mL), followed by the addition of a solution of N-(3-fluorobenzoyl)pyrrolidine (5.0 g, 25.9 mmol) in a minimum volume of THF. The resulting reaction mixture was stirred at -90° C. for 15 min, then TMSCl (6.75 g, 62.2 mmol) was added in a single portion. The reaction was warmed to RT, quenched with dilute aq citric acid, then was extracted with ether (3×). The combined ether extracts were dried (MgSO4), concentrated, and purified by HPLC with 3:7 EtOAc/hexanes to afford 0.45 g of the title compound as an oil, a 45% yield, which solidified on standing to a white solid. m.p. 97°-100° C.
