Reaction Conditions

Reaction Steps

To a solution of 2-(3-chlorophenyl)acetic acid (10 g, 58.6 mmol) in THF (58 ml) was added 117 mL of a 1M solution of sodium bis-(trimethylsilyl) amide in THF slowly over 1 h at −78° C. After being stirred at −78° C. for 40 min, a solution of methyl 4-chlorobenzoate (10 g, 58.6 mmol) in THF (35 ml) was added over a period of 10 min. The reaction was stirred at −78° C. for 3 h, then allowed to warm to 25° C., and stirred an additional 2 h until completion. The reaction was quenched with saturated aqueous NH4Cl solution and most of the THF was removed under reduced pressure. The residue was extracted with ethyl acetate (2×100 ml). The combined organic layers were washed with sat. NaCl solution, dried over Na2SO4, filtered and the filtrate was concentrated. The product was recrystallized from ether/pentane to provide the title compound as a white solid.
