4-Methoxybenzyl alcohol (11.9 mL, 95.2 mmol) was dissolved in DMF (150 mL), and at 0° C., 55% sodium hydride (4.15 g, 95.2 mmol) was added thereto, followed by stirring at room temperature for 1 hour. A DMF (10 mL) solution of 6-chloronicotinic acid (5.00 g, 31.7 mmol) was added to the reaction mixture, followed by stirring at 80° C. for 2 hours. Water (200 mL) was added to the reaction mixture, and 4 mol/L hydrochloric acid (30 mL) was added dropwise thereto, and the precipitated solid was collected by filtration to afford 6-(4-methoxybenzyloxy)nicotinic acid (8.15 g, 99%).
