Fa'aaogā:
E masani ona faʻaaogaina i le faʻaogaina o meaola o se mea taua tele. E mafai ona faʻaaogaina e faʻapipiʻi ai vailaʻau, vailaʻau faʻamaʻi ma isi mea faʻapitoa.
Metotia:
O le auala o le sauniuniga e faapea:
1. E ala i le 2-fluoropyridine ma se aofaʻi o le methyl bromide i le i ai o le chlorine faʻamaʻi poʻo le carbon peroxide.
2. E saunia e ala i le tali atu o le 2-bromo-5-fluoropyridine ma le methyl lithium.
Fa'amatalaga Saogalemu:
Atonu e ita ma pala i le tino o le tagata, o lea e tatau ai ona e gauai atu i tulaga saogalemu pe a faʻaaogaina, e aofia ai le ofuina o totigilima puipui, mata tioata ma lavalava puipui. Aloese mai le manavaina o ana ausa pe faʻafesoʻotaʻi ma paʻu ma mata. Afai e manavaina pe a'afia i le paluga, fufulu vave le vaega o lo'o a'afia ma saili fesoasoani fa'afoma'i pe a mana'omia.
