Reaction Steps
Sodium hydride (60% in oil, 0.31 g, 7.65 mmol) was added to DMF (5 ml) solution of 2,6-dichloro-4-trifluoromethylaniline (0.80 g, 3.48 mmol), followed by stirring for 30 minutes. Then, 3-methyl-2-methylthio-6-trifluoromethyl-4(3H)-pyrimidinone (0.70 g, 3.13 mmol) was added, followed by stirring at 50° C. for 8 hours. After completion of the reaction, 1 N hydrochloric acid (30 ml) and ethyl acetate (20 ml) were added to the reaction solution to separate the organic layer, and the resulting aqueous layer was extracted with ethyl acetate (50 ml). The organic layers were combined, washed with water (30 ml×2) and saturated brine (70 ml) and then dried over anhydrous magnesium sulfate. The drying agent was removed by filtration, and the resulting filtrate was concentrated under a reduced pressure. By recrystallizing the thus obtained crude product from toluene and then from chloroform, white solid of 2-(2,6-dichloro-4-trifluoromethylphenyl)amino-3-methyl-6-trifluoromethyl-4(3H)-pyrimidinone [Compound No. 28] was obtained.
