반응 단계

The procedure of Example 1 was followed using methyl nicotinate (2.74 g, 20 mmol), potassium trimethylsilanolate (2.56 g, 20 mmol), dry tetrahydrofuran (50 mL), and a 5 h reaction time. Potassium nicotinate (2.93 g, 90% yield) was isolated as a white solid: 1H NMR (D2O, DSS) δ 7.55 (ddd, J=1.0, 5.3, 8.3 Hz, Ar--H, 1H), 8.25 (dt, J=1.9, 8.3, Ar--H, 1H), 8.93 ppm (m, Ar--H, 1H). Anal. Calcd. for C6H4KNO2 : C, 44.70; H, 2.50; N, 8.96; K, 24.26. Found: C, 42.28, 42.51, 44.97; H, 2.95, 2.74, 2.83; N, 8.54; K, 24.57.
