Procedure

To a solution of 2-acetyl-5-methacrylamidosalicylic acid and 1% by weight of hydroquinone in methanol was added 0.5% by weight of concentrated sulfuric acid, and the solution was subject to reflux for several hours. After evaporating the solvent, the remaining residue was recrystallized by a mixture of water and methanol to give methyl 2-acetyl-5-methacrylamidosalicylate.
