Reaction Steps
Into 40 ml of anhydrous ethyl ether, was dissolved 7.1 g of 4-hydroxy-2-methylbenzoic acid followed by 21.3 g of acetic anhydride. The solution was stirred for 2.4 hours at room temperature. The reaction mixture was freed from the solvent under reduced pressure. The residue was admixed with hot water, then allowed to cool, and extracted with ethyl ether. The organic layer was washed with 2% hydrochloric acid, dried over anhydrous magnesium sulfate, and freed from the solvent by distillation under reduced pressure. The residue was recrystallized from an ethyl ether-petroleum ether mixture to obtain 7.5 g of 4-acetyloxy-2-methylbenzoic acid.
