Intangiriro
2-Bromo-4-methyl-5-nitropyridine ni ifumbire mvaruganda. Ibikurikira nintangiriro yimiterere yabyo, imikoreshereze, uburyo bwo gutegura namakuru yumutekano:
Ubwiza:
2-Bromo-4-methyl-5-nitropyridine ni ikintu gikomeye gifite kristu y'umuhondo. Ku bushyuhe bwicyumba, ntibikunze kuboneka mumazi, ariko birashobora gushonga mumashanyarazi nka Ethanol na dimethylformamide.
Koresha:
Uru ruganda rukunze gukoreshwa nkurwego rwo hagati muri synthesis. Irashobora gukoreshwa mugutegura izindi azote zirimo ibinyabuzima bya heterocyclic, nka pyrroles na indoles.
Uburyo:
2-Bromo-4-methyl-5-nitropyridine irashobora gutegurwa nigisubizo cyo gusimbuza aniline. Mugihe gikwiye, aniline ikorwa na acide ya bromoacetic kugirango ikore 2-bromoaniline. Noneho, na alkylation mubihe bya alkaline, 2-bromoaniline alkylated kugirango ibone 2-bromo-4-methylaniline. Ibisubizo bivamo 2-bromo-4-methylaniline ni nitrifitike na nitrification kugirango ibone 2-bromo-4-methyl-5-nitropyridine.
Amakuru yumutekano:
2-Bromo-4-methyl-5-nitropyridine ni ifumbire mvaruganda kandi igomba kubikwa no gukoreshwa neza. Nibintu bishobora gutwikwa kandi bigomba kubikwa kure yumuriro nubushyuhe bwinshi. Mugihe cyo gukora, kwirinda uruhu, amaso, hamwe nubuhumekero bigomba kwirindwa, kandi kubaga bigomba gukorwa mubihe bihumeka. Uturindantoki turinda, amadarubindi na masike bigomba kwambarwa mugihe bikoreshwa. Mugihe uhuye nimpanuka, kwoza ako kanya n'amazi menshi hanyuma ushakire kwa muganga.
