Versuchsvorschrift

To a stirred solution of N-acetyl-2-amino-benzylalcohol (20 g) in dry CHCl3 (500 mL) was added MnO2 (160 g, 8 equivalents) and allowed to stir at room temperature for 12 h. The reaction mixture was filtered through celite and concentrated. The crude product was recrystallised from CHCl3/petrol ether to give N-acetyl-2-aminobenzaldehyde (14 g, 73%).
