With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.59434-19-4,4-Aminophthalide,as a common compound, the synthetic route is as follows.

59434-19-4, To a stirred mixture of 4-((diethylamino)methyl)benzaldehyde (3.7 g, 19.4 mmol) and anhydrous magnesium sulfate (11.6 g, 96.8 mmol) in anhydrous acetonitrile (100 mL) was added 4-aminoisobenzofuran-1(3H)-one (2.89 g, 19.4 mmol) at 0 C. After the addition the mixture was stirred refluxed for 3 days. The mixture was filtered and the cake was washed with ethyl acetate (50 mL¡Á3). The filtrate was concentrated to give crude product, which was re-crystallized from isopropanol to give the title compound (2.1 g, yield: 32%). LC-MS (ESI) m/z: 323 (M+1)+
