Procedure

4-Chloro-6-(4-nitrophenoxy)pyrimidine (2.33 g, 9.25 mmol), 4-(methylthio)aniline (1.29 g, 9.25 mmol) and diisopropylethylamine (1.79 g, 13.9 mmol) were heated and stirred in 1-methylpyrrolidone (10 ml) at 80° C. for 18 hours. The reaction solution was distributed between ethyl acetate and water, the organic layer was washed with 1N aqueous sodium hydroxide, water and saturated brine and dried over anhydrous magnesium sulfate, the drying agent was filtered off and the filtrate was distilled off under reduced pressure. The obtained crude product was subjected to silica gel column chromatography (eluent—ethyl acetate:hexane=1:3), the fraction containing the target substance was concentrated and suspended in ethyl acetate, the suspension was diluted with hexane and the crystals were filtered out, washed with hexane and blow-dried to obtain the title compound (620 mg, 1.75 mmol, 19%) as colorless crystals.
