Hydrogenate 3.72 of 7-(4-nitrobenzyl)perhydroazepin-2-one in 50 mls of ethyl alcohol with platinum/hydrogen. After the absorption of hydrogen has ceased, filter off the catalyst and concentrate the filtrate. Dissolve the thus obtained 7-(4-aminobenzyl)-perhydroazepin-2-one in tetrahydrofuran. Add 680 mg of lithium aluminum hydride and boil the mixture under reflux. After cooling, treat it with ice-water and extract it with diethyl Dry the organic phase over sodium sulphate and concentrate it to obtain 2.0 g of the brown oily title compound.
