反应详情

To a mixture of 4-aminophenol (218 mg, 2 mmol) and 4-chloropyridin-2-amine (256 mg, 2 mmol) in DMSO (2.5 mL) was added NaOCH3 (216 mg, 4 mmol). The reaction was microwaved at 180° C. for 40 minutes, then cooled down to rt and quenched with water (10 mL). The mixture was extracted with EtOAc (10 mL×3). The combined organic phases were dried over anhydrous Na2SO4 and concentrated in vacuo. The residue was purified by a silica gel column chromatography (DCM/CH3OH (v/v)=30/1) to give the title compound as a brown solid (103 mg, 26%).
