Reaction Steps
A mixture of 1.0 g of 3-amino-5-trifluoromethylpyridine-2-carboxylic acid amide, 850 mg of 2-ethylsulfanylbenzaldehyde, 1.60 g of sodium bisulfite and 3 ml of DMA was stirred at 150° C. for 20 hours. Water was added to the cooled reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with water, then dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The resulting residue was applied to a silica gel column chromatography to obtain 927 mg of 2-(2-ethylsulfanylphenyl)-7-trifluoromethyl-3H-pyrido[3,2-d]pyrimidin-4-one.
