実験手順
A mixture containing 5-methylpyridin-2-amine (5.4 g, 50 mmol), phthalic anhydride (8.88 g, 60 mmol) and DIEA (19 ml, 110 mmol) in toluene (30 ml) is refluxed for 18 hours, and cooled. The solvent is removed by rotary evaporation. The crude product is purified by silica gel flash chromatography to afford 2-(5-methylpyridin-2-yl)isoindoline-1,3-dione as a dark brown oil. LC-MS m/z: 239.1 (M+1).
