The procedure of Example 1 was followed using methyl 4-chlorobenzoate (13.65 g, 80 mmol), potassium trimethylsilanolate (10.26 g, 80 mmol), dry ether (500 mL) and a 4 h reaction time. Potassium 4-chlorobenzoate (13.1 g, 84% yield) was isolated as a white solid: 1H NMR (D2O, DSS, 80 MHz) δ 7.68 ppm (ABq, Δν1-3 =29 Hz, J=8.5 Hz, Ar--H's, 4H). Anal. Calcd. for C7H4ClKO2 : C, 43.19; H, 2.07. Found: C, 43.27; H, 2.33.
