Procedure

A mixture of 1-ethoxycarbonyl-1,3-propano-2-indanone oxime (1.9 g.) and lithium aluminum hydride (1.6 g.) and 100 ml. of tetrahydrofuran is heated at its reflux temperature under dry nitrogen for 40 hours and allowed to stand for 3 days at room temperature. A few ml. of concentrated aqueous ammonia is added and after 15 minutes stirring the mixture is filtered. The filter cake is washed twice with isopropanol containing a little ammonia. The combined filtrates are concentrated to give 1.6 g. of oil which when treated with hydrogen chloride in ether and ethanol gives 1.2 g. of crystalline hydrochloride salt of the title product with m.p. 217°-220°.
