Selelekela

2-Bromo-4-methyl-5-nitropyridine ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa sebopeho sa eona, tšebeliso, mokhoa oa ho lokisa le tlhaiso-leseling ea polokeho:

 

Boleng:

2-Bromo-4-methyl-5-nitropyridine ke ntho e tiileng e nang le likristale tse mosehla. Mocheso oa kamore, ha se hangata o qhibilihang ka metsing, empa o ka qhibiliha ka har'a metsoako ea tlhaho e kang ethanol le dimethylformamide.

 

Sebelisa:

Motsoako ona o atisa ho sebelisoa e le setsi sa organic synthesis. E ka sebelisoa ha ho lokisoa metsoako e meng ea heterocyclic e nang le naetrojene, joalo ka pyrroles le indoles.

 

Mokhoa:

2-Bromo-4-methyl-5-nitropyridine e ka lokisoa ke karabelo ea sebaka sa aniline. Tlas'a maemo a loketseng, aniline e sebetsanoa le asiti ea bromoacetic ho hlahisa 2-bromoaniline. Joale, ka alkylation tlas'a maemo a alkaline, 2-bromoaniline e alkylated ho fumana 2-bromo-4-methylaniline. Sephetho sa 2-bromo-4-methylaniline se naetrification ka nitrification ho fumana 2-bromo-4-methyl-5-nitropyridine.
