N-formyl derivative 4 yabonetse muguhindura 2 muri acide formique kumasaha 5 kumusaruro mwinshi.Acide Acetike N '-Ifumbire ya 6 nayo iboneka muguhindura 2 hamwe na 3- (2-bromoacetyl) -4-hydroxy-2 H-chromen-2-imwe muri Ethanol.Ifumbire ya 2 ikora hamwe na fenyl isothiocyanate muri Ethanol mubushyuhe bwicyumba kugirango ibone 4-fenyl-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), Umusaruro wari 48% (Ihitamo 2).Imiterere yibintu 4-8 byagenwe namakuru yisesengura hamwe na IR hamwe na 1 H-NMR.Kwinjira kwa infragre kubera imikorere ya NH, OH na C = O bigaragara kuri 3450-3000 na 1728-1610cm-1.Absorption bande ijyanye no kuba hari andi matsinda akora arahari mukarere kateganijwe.Ikirangantego 1 H-NMR cyerekana ibice byerekana impinga imwe mukarere ka 8.03-10.58ppm ihuye na NH na OH proton.Guteranya 4-8
