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

I-N-formyl derivative 4 yafunyanwa nge-reflux ye-2 kwi-asidi ye-formic kwiiyure ze-5 kwisivuno esiphezulu.I-acetic acid N'-[2- (7-hydroxy-2-oxo-2 H-chromen-4-yl) -acetyl] -hydrazide (5) ifunyenwe nge-reflux acetylation ye-2 kwi-acetic acid kwisivuno esihle.I-Compound 6 iphinda ifunyenwe ngokuhlaziya i-2 kunye ne-3- (2-bromoacetyl) -4-hydroxy-2 H-chromen-2-enye kwi-ethanol.I-Compound 2 isabela nge-phenyl isothiocyanate kwi-ethanol kwiqondo lokushisa legumbi ukufumana i-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), Isivuno sasiyi-48% (Ukhetho lwe-2).Ukwakhiwa kwee-compounds 4-8 kunqunywe yidatha yabo yokuhlalutya kunye ne-IR yabo kunye ne-1 H-NMR spectra.I-infrared absorption ngenxa ye-NH, OH kunye ne-C = O imisebenzi ibonakala kwi-3450-3000 kunye ne-1728-1610cm-1, ngokulandelanayo.Iibhendi zokufunxa ezinxulumene nobukho bamanye amaqela asebenzayo akhoyo kwindawo elindelekileyo.I-spectrum ye-1 ye-H-NMR ye-compound ibonisa i-peak eyodwa kwindawo ye-8.03-10.58ppm ehambelana ne-NH kunye ne-OH protons.Umdibaniso 4-8
