When the addition has been completed, the mixture is maintained under reflux for 6 hours and, while cooling with ice, 5 ml of water, 5 ml of 15% sodium hydroxide solution and 15 ml of water are added thereto. The white precipitate which has formed is filtered off and boiled up 3 times with dichloromethane. The organic filtrates are combined, dried over magnesium sulphate and concentrated to dryness by evaporation in vacuo. The N-(6-methoxyindan-1-ylmethyl)amine which is obtained as an oily residue is converted into the hydrochloride with ethereal hydrochloric acid and recrystallised from isopropanol/diethyl ether. The pure 6-methoxyindan-1ylmethylammonium chloride melts at 129°-131°.
