実験手順
A solution of 7-acetoxy-1,3,4,5,6,7-hexahydro-1-benzazonin-2-one (7.4 g) in ethanol (250 ml) is hydrogenated at 45 psi at 70° C. using 10% palladium on charcoal (1.5 g) as catalyst. The catalyst is filtered off and the solvent removed under reduced pressure. The residue is recrystallized to give 1,3,4,5,6,7-hexahydro-1-benzazonin-2-one.
