Versuchsvorschrift

The solution of 0.84 g of 1-(2-oxopropyl)-9-methoxy-3-methyl-3,4,5,5a,6,7-hexahydro-2H-naphth[1,2-d]azepine hydrochloride, 1.28 ml of isopropylamine, 0.66 ml of 4.4 N methanolic hydrochloric acid and 0.17 g of sodium cyanoborohydride in 13 ml of methanol is refluxed overnight. Additional 0.085 g of sodium cyanoborohydride are added and the whole is again refluxed for 5 hours. The mixture is cooled, acidified to pH=1 with concentrated hydrochloric acid and the methanol evaporated. The aqueous solution is washed with diethyl ether, rendered basic to pH=10-11 with 3 N aqueous sodium hydroxide and extracted with diethyl ether. The ether extract is evaporated, the residue dissolved in acetone and 0.4 ml of 8 N ethanolic hydrochloric acid are added, to yield the 1-(2-isopropylaminopropyl)-9-methoxy-3-methyl-3,4,5,5 a,6,7-hexahydro-2H-naphth[1,2-d]azepine dihydrochloride melting at 257°-260° with decomposition.
