実験手順

To a solution of N2-(6-chloropyrimidin-4-yl)pyridine-2,6-diamine (200 mg, 0.90 mmol) in dry DMF (2 mL) was added 4-methoxyphenol (168 mg, 1.3 mmol) and anhydrous K2CO3 (179 mg, 1.3 mmol). The reaction mixture was heated at 100° C. for 16 h under N2 atmosphere. It was then cooled and DMF removed under reduced pressure to give a yellowish gummy residue that was taken in EtOAc (10 mL). The solution was washed with water (5 mL) and brine (5 mL), was dried over Na2SO4 and was then concentrated under reduced pressure to get crude product. This was further purified by column chromatography (SiO2, 60-120, hexane/EtOAc, 5/5) to give N2-(6-(4-methoxylphenoxy)pyrimidin-4-yl)pyridine-2,6-diamine (160 mg, 59.2%) as a pale yellow solid.
