Participants

Reaction Steps

Ethanethiol (0.62 g., 10 mmoles), dissolved in dimethyl formamide (10 ml.) is added to a suspension of sodium hydride (0.5 g. of 50% oil dispersion) in dry dimethyl formamide (5 ml.). The mixture is stirred until all hydrogen has evolved and 9-methoxy-11H-pyrrolo[2,1-b][3]benzazepin-11-one (2.26 g., 10 mmoles) is added. The solution is refluxed for a period of 3 hours. The cooled reaction mixture is acidified with 0.2N HCl and extracted with chloroform. The organic layer is washed with water, dried over sodium sulfate and concentrated to yield 9-hydroxy-11H-pyrrolo[2,1-b][3]benzazepin-11-one.
