New synthetic route to N,N-disubstituted 3-aryl-3-pyridylpropylamines: Pheniramines from 3-aryl-3-(2-pyridyl)propanals

3-Aryl-3-(2-pyridyl)propanals 3, useful precursors compound for the H1 antihistaminic agents Pheniramines 1 were prepared following three different reaction pathways: the first one involves the rhodium catalyzed regiospecific hydroformylation of cinnamaldehyde acetals 4; the second one was carried out through the hydro-hydroxyacetamidation reaction on 1-aryl-1-(2-pyridyl)ethenes 2 followed by oxidative cleavage of the intermediate α-hydroxybutanamides 10; the third one was accomplished through alkylation of 2-benzylpyridines 12 with 2-bromomethyl-1,3-dioxolane 13 using LDA as deprotonating agent. The last preparative route showed to be the most convenient giving Pheniramine 1 up to 80 percent overall yield.
