Reaction Steps

Sulfuryl chloride (0.16 ml) was added to acetic acid (14 ml) solution of 2-{2,5-bis(trifluoromethyl)phenyl}amino-3-isobutyl-6-trifluoromethyl-4(3H)-pyrimidinone (630 mg, 1.41 mmol), followed by stirring at room temperature for 3 hours. After completion of the reaction, ether (50 ml) and saturated sodium bicarbonate aqueous solution (50 ml) were added to the reaction solution to separate the organic layer, and the resulting aqueous layer was extracted with ether (30 ml×2). The thus obtained ether layers were combined, washed with sodium bicarbonate aqueous solution (50 ml) and saturated brine (50 ml) and dried over anhydrous sodium sulfate, and then the solvent was evaporated under a reduced pressure. By purifying the thus obtained crude product by a column chromatography (dichloromethane:hexane=7:3), white solid of 2-{2,5-bis(trifluoromethyl)phenyl}amino-5-chloro-3-isobutyl-6-trifluoromethyl-4(3H)-pyrimidinone [Compound No. 57] was obtained.
