Ethyl[7-(3-chlorophenyl)-1-oxo-1,2,3,4-tetrahydropyrrolo[1,2-a]pyrazin-4-yl]acetate (280 mg, 0.84 mmol) was dissolved in DCM, cooled in an ice bath and CF3COOAg (186 mg, 0.84 mmol) and Iodine (214 mg, 0.84 mmol) were added. The reaction was then warmed up at room temperature and after 1 hour was complete. It was filtered through paper, evaporated and the crude purified by silica chromatography (eluent: Hexane/AcOEt 3/2) to give 228 mg of desired product (59% yield).
