Abstract
5,6-Di(o-methoxylanilino) pyridine-2,3-dione was synthesized via the reaction of 3-hydroxy-2 (1H)- pyridinones with aromatic amine in the present of NaIO3 under solvent-free conditions by grinding. The structure of the product was characterized by 1H NMR and X-ray single crystal diffraction. The crystal belongs to monoclinicsystem, it has the characters,space group P21/n with a = 1.165 5(2) nm, b = 0.720 80(10) nm, c = 2.032 6(4) nm, α = 90°, β= 92.17(3)°, γ= 90°, V =1.706 3 (5) nm3, Z =4, F(000) =736, Mr = 351.36, Dc = 1.368 g/cm3, μ= 0.098 mm-1, R1 =0.058 7, wR2 = 0.136 5.
