실험 절차

The procedure of Example 1 was followed using methyl 4-chlorobenzoate (4.3 g, 25.2 mmol), lithium trimethylsilanolate (2.42 g, 25.2 mmol), and dry toluene (100 mL) and overnight heating at reflux. Lithium 4-chlorobenzoate (1.9 g, 46% yield) was isolated as a white solid: 1H NMR (D2O) δ 7.4 (ABq, Δν1-3 =31 Hz, J=9 Hz, Ar--H's, 2 H). This solid was contaminated with a small amount of lithium trimethylsilanolate.
