One-pot multicomponent reactions of acetylferrocene, (un)substituted benzaldehyde and malononitrile in refluxing ethanol with ammonium acetate as a catalyst gave 2-amino-3-cyano-4- [(un)substituted phenyl]-6-ferrocenylpyridines in moderate yields. Eight ferrocenyl pyridine derivatives were prepared efficiently and one single crystal structure of 4e was determined.

Key words: multicomponent reaction, ferrocene, pyridine, malononitrile, benzaldehyde, one-pot reaction
