Idatha Yezokuphepha
Okujwayelekile

Isicelo
I-metabolite ye-Diazepam;ibe nomphumela obuthakathaka kakhulu we-anticonvulsant.

Abaphakathi kwezemithi.Ukukhiqizwa kwezidakamizwa ezifana ne-Librium ne-Valium.
Umthelela wendawo
Iyingozi kancane emanzini, ungavumeli amanzi angaxutshiwe noma amakhulu ukuthintana namanzi angaphansi komhlaba, imigudu yamanzi noma indle, futhi ungachithi izinto ezisetshenziswayo endaweni ezungezile ngaphandle kwemvume kahulumeni.

Izakhiwo Nozinzo
Izinzile ezingeni lokushisa elizungezile nokucindezela, gwema ukuthintana nama-oxide

Izindlela zokugcina
Gcina isitsha sivalwe ngokuqinile futhi usigcine endaweni epholile, eyomile esitsheni esipakishwe ngokuqinile.

Indlela yokuhlanganisa
(1) Ikhiqizwe ukusabela kwe-p-chloroaniline nge-benzoyl chloride.Faka i-p-chlorobenzene ebhodweni lokusabela elinengilazi elingu-70°C noma ngaphansi, faka i-anhydrous zinc chloride, engeza i-benzoyl chloride dropwise ngokushukumisa, bese uphakamisa izinga lokushisa, ubambe ku-195-205°C amahora angu-2, geza kahlanu amanzi ashisayo ku-90-95 ° C (ungqimba lwamanzi kanye nesisombululo sokugeza kubuyisela i-benzoic acid ne-zinc chloride) cishe ku-100 ° C, engeza i-sulfuric acid kancane, ubambe ku-142 ° C imizuzu engu-40.Izinto eziqinile zigcwala emanzini.Ngaphansi kokunyakaziswa, i-pH ilungiswa nge-alkali ewuketshezi ingabi ngaphezu kuka-1 futhi ihlungwe ku-20-25 °C.I-filtrate itholakala njenge-p-chloroaniline.Ikhekhe lesihlungi liyaxutshwa futhi lilengiswe emanzini, lincishiswe libe yi-pH=6, lihlungwe lome, ligezwe ngamanzi ukuze lingathathi hlangothi futhi lomiswe ukuze kutholwe umkhiqizo ongahluziwe.Bese wengeza izikhathi ezingu-6-7 i-ethanol, i-6% ye-carbon activated, i-reflux ye-30min, isihlungi bese ucwebezela, yomile ukuze uthole umkhiqizo omuhle.(2) inhlanganisela ye-p-Nitrochlorobenzene ne-cyanobenzyl ukuze uthole i-isoxazole, bese uvula indandatho, ukuncishiswa ukuthola.
