摘要

Abstract 1-and 3-Substituted imidazo [4, 5-b] pyridin-2-ones were synthesized by heating equimolar amounts of 3-amino-2-chloropyridine or 2-chloro-3-methylaminopyridine, urea, and the corresponding arylamine at 150–210° C. The reaction of 3-amino-2-chloropyridine with urea and p-phenylenediamine or p, p′-diaminobiphenyl at a ratio of 2: 2: 1 under analogous conditions gave 1, 4-bis-(2-oxoimidazo [4, 5-b] pyridin-3-yl) benzene or 1, 4-bis ...
