Alfa Aesar 3,5-Dibromopyridine, 98+%
Manufacturer: Alfa Aesar A1087522
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 ft.-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.
