With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.80278-67-7,Isoquinoline-5-carbaldehyde,as a common compound, the synthetic route is as follows.
General procedure: To a dried two-neck round-bottom flask containing DMF (0.7mL for 1.10mmol of starting material) chilled in an ice bath, POCl3 (1.95 equiv) was added slowly. After stirring for 20min, a solution of an indole derivative (1.0 equiv) in DMF (3mL for 1.10mmol of starting material) was added dropwise. The reaction was allowed to warm to room temperature and allowed to stir for 1.5h. The reaction was quenched by adding ice followed by 1N NaOH (40mL) dropwise in an ice bath. The crude mixture was allowed to stand at room temperature and the precipitate formed was filtered to afford the 3-formyl-indole derivative product.
As the paragraph descriping shows that 80278-67-7 is playing an increasingly important role.
