Versuchsvorschrift
The solution of 1 g of ethyl 3,3-dimethylindoline-2-carboxylate hydrochloride in 25 ml of ethanol is saturated with anhydrous ammonia and heated in a closed vessel to 50° for 4 days. It is evaporated, the residue crystallized from diethyl ether, suspended in water and 3N aqueous sodium hydroxide is added to render the mixture basic. It is extracted with methylene chloride, the extract dried and evaporated, to yield the 3,3-dimethylindoline-2-carboxamide melting at 156°-158°.
