in tetrahydrofuran

Steps:

10 Potassium benzoate
EXAMPLE 10 Potassium benzoate The procedure of Example 1 was followed using phenyl benzoate (3.96 g, 20 mmol), potassium trimethylsilanolate (2.56 g, 20 mmol), dry tetrahydrofuran (50 mL), and a 5 h reaction time. Potassium benzoate (2.37 g, 74% yield) was isolated as a white solid: 1 H NMR (D2 O, DSS, 80 MHz) δ 7.4-8.0 (m, Ar--H's, 5H). Anal. Calcd. for C7 H5 KO2: C, 52.48; H, 3.15; K, 24.41, Found: C, 50.28, 50.15, 52.45; H, 3.28, 3.36, 3.24; K, 24.80.
