Versuchsvorschrift

Under N2, a pale yellow suspension of crude N-(2-acetylphenyl)acetamide (28 g, 158 mmol) in AcOH (300 mL) was stirred for about 5 min, and Br2 (12.95 mL, 253 mmol) was added within 1 h at room temperature. The resulting mixture was then stirred at room temperature for 75 min. After the reaction went to completion as monitored by LC-MS, the reaction mixture was quenched with H2O (200 mL). The mixture was filtered through Buchner funnel, and the solid was collected as N-(2-acetyl-4-bromophenyl)acetamide (35 g, yield 86%). MS (m/z): 216 (M+H)+.
