Nzira:
Nzira yekugadzirira ndeyotevera:
1. Ne 2-fluoropyridine uye imwe chiyero chemethyl bromide pamberi pe oxidant chlorine kana carbon peroxide reaction.
2. Yakagadzirirwa nekuita kwe2-bromo-5-fluoropyridine uye methyl lithium.
Zvekuchengetedza
Zvinogona kunge zvichitsamwisa uye zvinosvibisa muviri wemunhu, saka unofanirwa kutarisisa matanho ekuchengetedza paunenge uchiishandisa, kusanganisira kupfeka magirovhosi ekudzivirira, magirazi uye zvipfeko zvekudzivirira. Dzivisa kufemba hutsi hwayo kana kubata neganda nemaziso. Kana ukafemerwa kana kusvuurirwa mukomboni, geza nzvimbo yabatwa nekukasika uye tsvaga rubatsiro kuna chiremba kana zvichidiwa.
