Abstract
The synthesis of a new Schiff base 5-methoxy-2-{(E)-[(3-methylpyridin-2-yl)imino]methyl}phenol based on the condensation reaction of 2-hydroxy-4-methoxybenzaldehyde and 2-amino-3-methylpyridine was investigated. Experimental results showed that the maximum yield was obtained by the reaction between 2- hydroxy-4-methoxybenzaldehyde and 2-amino-3-methylpyridine with a molar ratio of 1:1 under the temperature of75 ℃ for 5 h. The structure of the target compound was characterized with IR,1H NMR and X-ray single crystal diffraction. The compound crystallizes in the monoclinic system, space group P21/n, with β = 96.54 o, a = 4.64(7) ,b = 28.23(4) , c = 9.46(14) , Dc= 1.30×103kg/m3, Z = 4, V = 1 230(3) 3, μ = 0.09 mm-1, R1= 0.10, w R2= 0.18.
