Procedure
Under the protection by nitrogen, meta-cyanobenzaldehyde (137.6 g, 1.05 mol), 7-chloroquinaldine (177 g, 1.0 mol) and sodium acetate (82 g) are added into 1000 ml of acetic anhydride, and the resulted mixture solution is stirred and heated to 125-135° C. for 24 hours. After distilling out the most of acetic anhydride, 300 ml of water is added into the residue, and then extracted by ethyl acetate (500 ml×3), washed with saturated saline water, dried with anhydrous sodium sulfate and condensed in the vacuum. The resulted residue is then purified through Flash Column Chromatography to obtain 266.8 g of the title compound, with a yield of 92%.
