Water → 2-(2,5-Dimethyl-1H-pyrrol-1-yl)ethan-1-amine

Participants

Reaction Steps

251.1 g (1.39 mol) of 2,5-dimethyl-1-(2-acetylaminoethyl)-pyrrole, prepared as in Example 5, and 390.8 g (6.97 mol) of potassium hydroxide are heated reflux in 2.8 l of ethanol and 180 ml of water under an atmosphere of nitrogen for 4 h. After the mixture has been concentrated, the aqueous phase is extracted with methylene chloride, and the extract is fractionally distilled. Yield: 150.2 g (78% of theory), Boiling point: 70° C./0.267 mbar
