Reaction Steps
To 150 ml methanol, was dissolved 2-chloro-4-methoxy-3-methylbenzoic acid in an amount of 16.6 g (0.0832 mole), and the resulting solution was stirred for 18 hours under reflux and heating following to the addition of concentrated sulfuric acid in an amount of 1.0 g into the solution. The residue obtained by distillating out the solvent under reduced pressure was dissolved in benzene, washed with 3% aqueous solution of sodium hydrogencarbonate and subsequently with saturated saline solution and dried with anhydrous magnesium sulfate. After distillating out the solvent in the solution under reduced pressure, the crystals remained were washed with methanol to obtain methyl 2-chloro-4-methoxy-3-methylbenzoate in an amount of 13.5 g. The yield was 76.0%.
