実験手順

To a solution containing methyl 4-phenylnicotinate (3.8 g, 17.8 mmol) from the previous step in methyl alcohol (20 mL) was added 1 N sodium hydroxide (21.4 mL). The mixture was stirred at room temperature for 6 hours, neutralized with 1 N hydrochloric acid, evaporated in vacuo and dried overnight to yield the solid 4-phenylnicotinic acid (4.7 g, Theo. Yield=3.6 g, balance is NaCl); HPLC RT=1.80 min, method A; LC-MS m/z=200; 1H NMR, 400 MHz, CD3OD, 8.91 ppm (s, 1H), 8.66 ppm (d, 1H), 7.48 ppm (d, 1H), 7.46-7.41 ppm (m, 5H).
