With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.387-43-9,4-Fluoroindole,as a common compound, the synthetic route is as follows.
To a solution DMF (0.670 ml8.653 mmol) in dichloromethane (2.5 mL) cooled to -15 ¡ãC was added dropwise phosphorus oxychloride (0.400 mL; 4.291 mmol). After 15 min at -15 ¡ãC, a solution of 4-fluoro-1 /-/-indole (0.500 g; 3.700 mmol) in dichloromethane (2 mL) was added. The reaction mixture was allowed to warm to room temperature and was stirred at room temperature overnight. A saturated sodium bicarbonate solution was added and the reaction mixture was extracted with dichloromethane. The organic phase was dried over magnesium sulfate, filtered and concentrated under reduced pressure. Purification by flash chromatography on silica gel using ethyl acetate (50percent) in heptane as eluent furnished 0.144 g (24percent) of 4-fluoro- 1 H-indole-3-carbaldehyde as a beige solid. ESI/APCI(+): 164. ESI/APCI(-): 162 (M-H).
387-43-9, As the paragraph descriping shows that 387-43-9 is playing an increasingly important role.
