반응 단계
2-(4-Bromo-3-oxo-butyl)-isoindole-1,3-dione is prepared by condensation of but-1-en-3-one with phthalimide followed by bromination according to known procedures (J. Med. Chem., 35:3239, 1992. A solution of 2-(4-bromo-3-oxo-butyl)-isoindole-1,3-dione (8.9 g, 30.06 mmol) and 2-aminopyridine (2.8 g, 29.75 mmol) in ethanol is heated at reflux for 4 hours. The mixture is cooled to room temperature and concentrated. The residue is purified by chromatography (silica gel, dichloromethane/ethanol 95:5); to give 4.23 g of 2-[2-(imidazo[1,2-a]pyridin-2-yl)ethyl]-isoindole-1,3-dione (49%).
