Daim ntawv thov

3, 5-dibromopyridine yog cov hmoov dawb mus rau lub teeb daj crystalline hmoov uas tuaj yeem siv los ua cov tshuaj nruab nrab.

{{0}}Acetylamino-5-ethoxypyridine tau npaj los ntawm kev hloov 3, 5-dibromopyridine nrog sodium ethylate rau hauv 3-bromo-5-ethoxypyridine, tso cai rau cov tshuaj no cuam tshuam nrog ammonia thiab acetylates cov aminoethoxypyridine yog li tsim nrog acetic anhydride. Lithiation ntawm 3, 5-dibromopyridine nrog LDA thiab cov tshuaj tiv thaiv tom qab nrog electrophiles muab 4-alkyl-3, 5-dibromopyridines 2 nyob rau hauv siab yield. Ligand tau npaj los ntawm Pd(0)-catalyzed cross-coupling cov tshuaj tiv thaiv ntawm 3,5-dibromopyridine thiab 5-tributylstannyl-3,3?-bipyridine. Lub synthesis ntawm 3, 5-bis (2-indolyl) pyridine thiab 3-[({25}}indolyl)-5- phenyl] pyridine derivatives xws li Stille lossis Suzuki hom cov tshuaj tiv thaiv, uas tau paub txog ntawm 3, 5-dibromopyridine.
