3-Acetylamino-5-ethoxypyridine was prepared by converting 3, 5-dibromopyridine with sodium ethylate into 3-bromo-5-ethoxypyridine, allowing this substance to interact with ammonia and acetylating the aminoethoxypyridine thus formed with acetic anhydride. Lithiation of 3, 5-dibromopyridine with LDA and subsequent reaction with electrophiles provided 4-alkyl-3, 5-dibromopyridines 2 in high yield. Ligand was prepared by a Pd(0)-catalyzed cross-coupling reaction of 3,5-dibromopyridine and 5-tributylstannyl-3,3?-bipyridine. The synthesis of 3, 5-bis (2-indolyl) pyridine and 3-[(2-indolyl)-5-phenyl] pyridine derivatives as includes Stille or Suzuki type reactions, which were realized on the 3,5-dibromopyridine.


Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents, alkali metals, moisture.

With n-BuLi at -30 o, selective metallation occurs by exchange with one Br atom: J. Org. Chem., 16,1485 (1951). In contrast, using LDA in THF at -100 o, lithiation can be accomplished at the 4-position. Subsequent reaction with an electrophile can be followed by lithiation with n-BuLi to give 3-bromo-4,5-disubstituted pyridines: Tetrahedron Lett ., 37, 2565 (1996):
