YieldReaction ConditionsOperation in experiment
92% In ethanol; for 4h; A solution of 1,5-bis(2-aminophenoxy)-3-oxopenthane (0.1974 g, 0.6838 mmol) in ethanol (20 mL) was added dropwise to a refluxing solution of <strong>[42059-80-3]6-nitro-4-oxo-4H-chromene-3-carbaldehyde</strong> (0.315 g, 1.43 mmol) in the same solvent. The resulting solution were gently refluxed with magnetic stirring for ca. 4 h at room temperature and then evaporated to dryness. The residues were extracted with water-chloroform. The organic phase was dried (MgSO4), filtered and solvent removal gave a yellow powder precipitate, which was then filtered off, washed with cold absolute ethanol and cold diethyl ether and dried under vacuum. After purification by chromatography column, the compound was characterized as (3).4.2.1.1. Compound (3)Yellow solid (92%). Anal. Calcd for C36H30N4O11·H2O: C, 60.62; H, 4.53; N, 7.81. Found: C, 60.61; H, 4.83; N, 7.41. MALDI-TOF/MS, [LH]+=691.37. IR (KBr) 3410 ν(N-H)st, 1647 ν(CN)imin, 1257 ν(C-O), 944 ν(C-O-C).
