CAS: 77472-71-0 2-Oxo-4-Phenyl-1-Pyrrolidineacetic Asid Hydrazide Phenylpiracetam hydrazin

N-formyl derive 4 te jwenn pa rflu nan 2 nan asid fòmik pou 5 èdtan nan yon sede segondè.Acetic asid N'-[2-(7-hydroxy-2-oxo-2 H-chromen-4-yl)-acetyl]-hydrazide (5) te jwenn pa acetylation rflu nan 2 nan asid acetic nan yon sede bon.Konpoze 6 jwenn tou nan reflux 2 ak 3-(2-bromoacetyl) -4-hydroxy-2 H-chromen-2-one nan etanòl.Konpoze 2 reyaji ak phenyl isothiocyanate nan etanòl nan tanperati chanm pou jwenn 4-phenyl-1-(7-hydroxy-2-oxo-2 H-chromen-4-acetyl -)-thiosemicarbazide (7).
3-{2-[2-(7-hydroxy-2-oxo-2 H-chromen-4-yl)-acetyl]hydrazono}butanoate (8) etil ester (8), 3-{2-[2-( 7-hydroxy-2-oxo-2 H-Chromen-4-yl)-acetyl] Hydrazono} Butanoate (8), Sede a te 48% (Opsyon 2).Estrikti konpoze 4-8 yo te detèmine pa done analyse yo ak spectre IR ak 1 H-NMR yo.Absòpsyon enfrawouj la akòz fonksyon NH, OH ak C = O parèt nan 3450-3000 ak 1728-1610cm-1, respektivman.Bann absòpsyon ki asosye ak prezans lòt gwoup fonksyonèl yo prezan nan rejyon espere a.Spectre 1 H-NMR konpoze an montre yon sèl pik nan rejyon 8.03-10.58ppm ki koresponn ak pwoton NH ak OH.Konpoze 4-8
