A suspension of 1,3,4,5-tetrahydro-6-hydroxy-2H-1-benzazepin-2-one (500 mg, 2.82 mmol) in 2.5 mL each of pyridine and acetic acid was stirred at room temperature. Excess reagents were removed under reduced pressure and the residue was triturated with CH2Cl2 to give 540 mg (87%) of 1,3,4,5-tetrahydro-6-acetoxy-2H-1-benzazepin-2-one; MS 219.
