The reaction of 3-formylchromones with aminoheterocycles was investigated. A simple and flexible general procedure for annulation of 5-(2-hydroxybenzoyl)pyridines was proposed. The best reaction conditions were found to be heating the reaction mixture in DMF in the presence of Me 3 SiCl as a promoter and water as scavenger.
