Reaction Steps

To a solution of methyl thiosalicylate (1.063 g, 6.32 mmol) in N,N-dimethylformamide (10 ml) were added 1-iodopentane (0.87 ml, 6.57 mmol) and potassium carbonate (0.997 g, 7.22 mmol), and the mixture was stirred at 80° C. for 5 hr. Ethyl acetate was added to the reaction mixture, the mixture was washed with water, and the organic layer was dried over sodium sulfate. The solvent was evaporated under reduced pressure, and the obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate) to give methyl 2-pentylthiobenzoate quantitatively. This was dissolved in methanol (15 ml), 1N-aqueous sodium hydroxide solution (15 ml) was added at room temperature, and the mixture was stirred at 50° C. for 1.5 hr. The reaction mixture was concentrated under reduced pressure and neutralized with 1N-aqueous hydrochloric acid solution, and the mixture was extracted with ethyl acetate. The extract was dried over sodium sulfate, and the solvent was evaporated under reduced pressure to give a carboxylic acid compound 2-pentylthiobenzoic acid (1.370 g, 6.11 mmol, yield 97%).
