To a solution of (2-((3-fluorophenyl)amino)-4-(propylamino)pyrimidin-5-yl)methanol (E13, 20 mg) and 3-nitrothiophenol (17 mg) in tetrahydrofuran (1 mL), tributylphosphine (36 μL) and 1,1′-(azodicarbonyl)dipiperidine (28 mg) were added under ice cooling, and the mixture was stirred at room temperature for 6 hours and 30 minutes. To the reaction mixture, tributylphosphine (36 μL) and 1,1′-(azodicarbonyl)dipiperidine (28 mg) were added at room temperature, and the mixture was stirred at the same temperature for 8 hours and 30 minutes. The solvent was evaporated under reduced pressure, and then the obtained residue was purified by basic silica gel column chromatography (eluent, 88 to 40% hexane in ethyl acetate) to obtain N2-(3-fluorophenyl)-5-(((3-nitrophenyl)thio)methyl)-N4-propylpyrimidine-2,4-diamine (E19, 19 mg) as yellow solid.
