Koresha:
Ikoreshwa cyane cyane muri synthesis organique nkingirakamaro hagati. Irashobora gukoreshwa muguhuza ibiyobyabwenge, imiti yica udukoko nibindi bintu kama.
Uburyo:
Uburyo bwo kwitegura nuburyo bukurikira:
1. Na 2-fluoropyridine hamwe numubare munini wa methyl bromide imbere ya okiside chlorine cyangwa reaction ya karubone peroxide.
2. Itegurwa nigisubizo cya 2-bromo-5-fluoropyridine na methyl lithium.
Amakuru yumutekano:
Irashobora kurakaza kandi ikabora umubiri wumuntu, bityo rero ugomba kwitondera ingamba zumutekano mugihe uyikoresheje, harimo kwambara uturindantoki turinda, ibirahure n imyenda ikingira. Irinde guhumeka umwuka wacyo cyangwa guhura nuruhu n'amaso. Niba ushizemo umwuka cyangwa uhuye nikigo, kwoza ako kanya uhite ushakira ubuvuzi nibiba ngombwa.
