59434-19-4, 4-Aminophthalide is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a stirred mixture of 3-(diethoxymethyl)benzaldehyde (3.75 g, 18 mmol) and anhydrous sodium sulfate (21.3 g, 150 mmol) in anhydrous dichloromethane (300 mL) was added 4-aminoisobenzofuran-1(3H)-one (2.24 g, 15 mmol) at 0 C. After the addition, the mixture was stirred at room temperature for 6 days. The mixture was filtered and the cake was washed with dichloromethane (50 mL¡Á3). The filtrate was concentrated to give crude product. The crude product was washed with petroleum ether to give (E)-4-(3-(diethoxymethyl)benzylideneamino)isobenzofuran-1(3H)-one (3.1 g, yield 61%) as a white solid. LC-MS (ESI) m/z: 340 (M+1)+
59434-19-4 4-Aminophthalide 12284649, abenzofuran compound, is more and more widely used in various.
