実験手順
The solution of 1 g of 1-(2-isopropyliminopropyl)-9-methoxy-3,4,5,5a,6,7-hexahydro-2H-naphth[1,2-d]azepin-2-one in 50 ml of ethanol is hydrogenated at room temperature and atmospheric pressure for 2 hours in the presence of 0.1 g of platinum dioxide catalyst. The mixture is filtered, the filtrate evaporated and the residue crystallized from petroleum ether, to yield the 1-(2-isopropylaminopropyl)-9-methoxy-3,4,5,5a,6,7-hexahydro-2H-naphth[1,2-d]azepin-2-one as a mixture of the "slow" and "fast" moving isomers, melting at 118°-126°.
