실험 절차

2.66 ml of glacial acetic acid are added dropwise to the ice-cooled mixture of 5.0 g of slow moving 1-(2-isopropylaminopropyl)-9-methoxy-3,4,5,5a,6,7-hexahydro-2H-naphth[1,2-d]azepin-2-one hydrochloride, 15.2 g of heptaldehyde, 2.52 g of sodium cyanoborohydride and 53 ml of acetonitrile. The mixture is stirred at room temperature for 2 hours, cooled, acidified to pH=1 with concentrated hydrochloric acid and evaporated to remove the acetonitrile. The residue is diluted with water, the solution washed with diethyl ether, basified to pH=10-11 with 3 N aqueous sodium hydroxide and extracted with chloroform. The extract is dried, evaporated and the residue crystallized from ethanol-water (5:2) to give the 1-[2-(N-isopropyl-N-heptylamino)propyl]-9-methoxy-3,4,5,5a,6,7-hexahydro-2H-naphth[1,2-d]azepin-2-one, RR racemate melting at 102°-104°.
