Folasaga
2-Bromo-4-methyl-5-nitropyridine o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i lona natura, fa'aoga, auala sauniuni ma fa'amatalaga saogalemu:
Tulaga lelei:
2-Bromo-4-methyl-5-nitropyridine o se mea mautu ma tioata samasama. I le vevela o le potu, e seasea solu i le vai, ae e mafai ona soluble i solvents organic pei ole ethanol ma le dimethylformamide.
Fa'aaogā:
O lenei tuufaatasiga e masani ona faʻaaogaina e avea o se vaeluaga i le faʻaogaina o meaola. E mafai ona faʻaaogaina i le sauniuniga o isi faʻalapotopotoga heterocyclic o loʻo i ai le nitrogen, e pei o pyrroles ma indoles.
Metotia:
2-Bromo-4-methyl-5-nitropyridine e mafai ona saunia e ala i le sui sui o le aniline. I lalo o tulaga talafeagai, o le aniline e tali atu i le bromoacetic acid e maua ai le 2-bromoaniline. Ona, e ala i le alkylation i lalo o tulaga alkaline, 2-bromoaniline ua alkylated e maua ai le 2-bromo-4-methylaniline. O le taunuuga o le 2-bromo-4-methylaniline e faʻamalosia e le nitrification e maua ai le 2-bromo-4-methyl-5-nitropyridine.
Fa'amatalaga Saogalemu:
2-Bromo-4-methyl-5-nitropyridine o se faʻalapotopotoga faʻapitoa ma e tatau ona teuina ma faʻaoga saʻo. Ose mea e mu ma e tatau ona 'alo'ese mai le mumū ma le vevela maualuga. I le taimi o le taotoga, e tatau ona aloese mai le faʻafesoʻotaʻi ma le paʻu, mata, ma le manava, ma e tatau ona faia le taotoga i lalo o tulaga faʻafefe. Totigilima puipui, mata tioata ma matapulepule e tatau ona ofuina pe a faʻaaogaina. A iai se fa'alavelave fa'afuase'i, fufulu vave i le tele o vai ma saili togafitiga faafoma'i.
