Reaktionsschritte

A mixture of 4.0 g (0.1M) of LAH and 400 ml of ether was stirred while a solution of 9.0 g (51 mmol) of 1-methylaminocarbonyl-indane, a compound of Formula 13 prepared, for example, as described in Preparation 13, dissolved 200 ml of THF was added over a period of 30 minutes. The reaction mixture was stirred and heated to reflux for 6 hours, and then stirred at ambient temperature for an additional 16 hours. The reaction mixture was then digested by treating dropwise with water, 15% NaOH, and then water, yielding 1-methylaminomethyl-indane, an intermediate amine of Formula 14; (HCl salt, ethanol-ether, mp 169°-171° C.).
