After MeOH (20 mL) was added to 2-mercapto-nicotinic acid (1 g, 6 mmol), the mixture was cooled to 0° C., and 6 M NaOH aqueous solution (3.2 mL) was added slowly thereto. The reactant was stirred at 0° C. for 30 minutes. 1-Iodobutane (0.74 mL, 6 mmol) was added to the reactant, and the mixture was stirred under reflux at 80° C. for 16 hours. The reactant was concentrated under reduced pressure, and 6 M HCl aqueous solution was added thereto to adjust the pH of the solution to 7. The resulting precipitate was filtered and dried to obtain the title compound (1.27 g, 93%).
