Versuchsvorschrift

To a solution of methyl 2-amino-3-hydroxybenzoate (882 mg) in pyridine (2 ml) was added acetic anhydride (1.2 ml) and the mixture was stirred at 20° C. for 8 hours. The reaction mixture was diluted with diisopropyl ether, and the resulting solid was collected and washed with diisopropyl ether. The solid was triturated with diisopropyl ether to give methyl 2-acetamido-3-acetoxybenzoate (1.25 g) as solid.
