Versuchsvorschrift

To a suspension of 5-bromo isatin (5 g, 20.5 mmol) and 2-acetylpyridine (2.5 g, 20.5 mmol) in aqueous KOH (1.2 g, 33%) was added EtOH until a solution formed. The mixture was refluxed over night. The reaction mixture was neutralized with HOAc (50%) and filtered. The solid was resuspended in EtOH and filtered to give the title compound (5.5 g). LC: 1.66 and MH+: 329.
