実験手順
2-Carboxy-11-(3-dimethylaminopropylidene)-11H-pyrrolo[2,1-b][3]benzazepine (99 mmoles) in 100 ml. of thionyl chloride is refluxed for 15 minutes. The volatiles are removed under vacuum and the residue is triturated in ether. Filtration and air drying yields 2-chlorocarbonyl-11-(3-dimethylaminopropylidene)-11H-pyrrolo[2,1-b][3]benzazepine.
