| - ated aldehyde, for example, cinnamaldehyde, in the presence of a reducing agent such as sodium triacetoxyborohydride to afford a compound of structure 55A. A palladium-catalyzed cyclization reaction catalyzed by, for example, palladium(II) acetate, affords a compound of structure 56A. Reduction of the nitro group with, for example, hydrogen over palladium on carbon, affords the aniline, and a Knor
