CAS: 77472-71-0 2-Oxo-4-Phenyl-1-Pyrrolidineacetic Acid Hydrazide Phenylpiracetam hydrazine

N-formyl derivative 4 yakawanikwa nereflux ye2 muformic acid kwemaawa mashanu pagoho rakakwirira.Acetic acid N'- [2- (7-hydroxy-2-oxo-2 H-chromen-4-yl) -acetyl] -hydrazide (5) yakawanikwa ne reflux acetylation ye 2 muacetic acid pane chibereko chakanaka.Compound 6 inowanikwawo nekugadzirisa 2 ne 3-(2-bromoacetyl) -4-hydroxy-2 H-chromen-2-one mu ethanol.Compound 2 inopindirana ne phenyl isothiocyanate mu ethanol pakupisa kwekamuri kuwana 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) ethyl ester (8), 3-{2-[2-( 7-hydroxy-2-oxo-2 H-Chromen-4-yl)-acetyl] Hydrazono} Butanoate (8), The goho was 48% (Option 2).Chimiro chemakomponi 4-8 chakatemwa neavo yekuongorora data uye yavo IR uye 1 H-NMR spectra.Iyo infrared absorption nekuda kweNH, OH uye C=O mabasa anoonekwa pa3450-3000 uye 1728-1610cm-1, zvichiteerana.Absorption mabhendi ane chekuita nekuvapo kwemamwe mapoka anoshanda aripo munharaunda inotarisirwa.Iyo 1 H-NMR spectrum yekomboni inoratidza imwe chete yepamusoro munharaunda ye8.03-10.58ppm inoenderana neNH uye OH protons.Musanganiswa 4-8
