Participants

Reaction Steps

0.25 g of methyl 2-chloro-4-hydroxybenzoate was dissolved in 10 ml dimethylformamide, and 0.23 g of ethyl iodide and 0.21 g of potassium carbonate were added, and the mixture was stirred for 8 hours. After diluting the reaction mixture, it was extracted with ethyl acetate. The organic layer was successively washed with 1N hydrochloric acid and brine, dried over anhydrous magnesium sulfate and the solvent was evaporated. The residue was dissolved in 6 ml methanol, and 3 ml of 1 N sodium hydroxide was added, and the solution was stirred at room temperature for 6 hours. The reaction mixture was ice-cooled and neutralized with 1N hydrochloric acid, followed by extracting with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate and the solvent was evaporated, to give 1.7 g of 2-chloro-4-ethoxybenzoic acid.
