Reaction Steps
Potassium carbonate (22.0 g, 159 mmol) and iodoethane (9.0 mL, 112 mmol) were added to a stirred solution of 5-methylthio-2-hydroxy-benzoic acid (5.00 g, 27 mmol) in 2-butanone (125 mL). The resulting mixture was heated in an oil bath (80° C.) for 16 h and then allowed to cool. The solution was concentrated and redissolved in methylene chloride. The organic phase was washed with water and brine, dried over anhydrous magnesium sulfate and concentrated. Purification of the crude residue by flash column chromatography (silica gel, eluting with 5-15% ethyl acetate in hexanes) gave ethyl 5-methylthio-2-ethoxybenzoate as a yellow oil (5.5 g, 85%).
