Reaction Steps
A mixture of 1.0 g of 2-amino-4-trifluromethylbenzamide, 944 mg of 4-chloro-2-ethylsulfanylbenzaldehyde, 765 mg of sodium bisulfite and 4 ml of DMA was stirred at 150° C. for 15 hours. A saturated aqueous sodium bicarbonate solution and water were added to the cooled reaction mixture, and the precipitated solid was filtered. The resulting solid was washed with water and n-hexane and then dried to obtain 1.46 g of 2-(4-chloro-2-ethylsulfanylphenyl)-7-trifluoromethyl-3H-quinazolin-4-one.
