Reaction Steps

Methylene chloride (5.0 mL), pyridine (0.25 mL), and acetic anhydride (0.19 mL) were sequentially added to the obtained 2-hydroxy-5-(pyridin-3-yl)benzoic acid, followed by heating to reflux for 1 hour. The reaction mixture was cooled to room temperature, and then pyridine (0.082 mL) and acetic anhydride (0.095 mL) were added thereto, followed by heating to reflux for 30 minutes. The reaction mixture was cooled to room temperature, and then the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography [Kanto Chemical Co., Inc., silica gel 60 (spherical), eluent: 99-93% chloroform/methanol] to obtain 0.035 g of 2-acetoxy-5-(pyridin-3-yl)benzoic acid as a white solid.
