Methanol → Methyl 4-chloro-2-hydroxybenzoate

참여 물질

반응 단계

5 ml of concentrated sulfuric acid is drop-added slowly to 100 ml of methanol. The solution is cooled and then added with a powder of 4-chloro-salicylic acid (17.20 g, 0.1 mol), and a reaction is carried out at reflux for 24 hours. After cooling the reaction, a large amount of deposit precipitates and is filtered out, washed with small amount of methanol, and recrystallized in anhydrous ethanol, to obtain 15.60 g of methyl 4-chloro-salicylate, with a yield of 83%.
