Reduce 3-azidoperhydroazocin-2-one (Example 3) to 3-aminoperhydroazocin-2-one using 10% Pd/C in ethanol. NMR (CDCl3, TMS): δ 1.67 (broad s, 8H), δ 2.25 (broad s, 2H), δ 3.35 (m, 2H), δ 3.8 (m, 1H), δ 7.0 (broad, 1H). Hydrogenate a solution of 1.42 g of this amine, 0.59 g acetic acid and 3.09 g ethyl 2-oxo-4-phenylbutyrate in 50 ml ethanol over 10% Pd/C catalyst. AFter filtration and concentration of the reaction, purify the product by chromatography over silica gel to isolate 3-[(1-ethoxycarbonyl-3-phenyl-1-propyl)amino]perhydroazocin-2-one.
