With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.79002-39-4,Benzofuran-5-carbonitrile,as a common compound, the synthetic route is as follows.

79002-39-4, EXAMPLE 20 Preparation of 1-benzofuran-5-carbaldehyde To a solution of 1-benzofuran-5-carbonitrile (5.0 g, 34.9 mmol) in CH2Cl2 under nitrogen at -15 to -20 C. was added DIBAL-H (41.9 mL, 41.9 mmol, 1 M/heptane) and the temperature was maintained below -15 C. After addition was complete, the reaction mixture was stirred at -15 to -20 C. for an additional 10 min. The reaction mixture was quenched via dropwise addition of aqueous 2N HCl. The organic layer was separated and washed with water, dried over sodium sulfate, and concentrated to give 4.0 g (78%) of 1-benzofuran-5-carbaldehyde as a yellow oil.

The synthetic route of 79002-39-4 has been constantly updated, and we look forward to future research findings.

EXAMPLE 15:PREPARATION OF 5-(5-FORMYL-I -BENZOFURAN-2-YL)-6-METHYL-4-[(4- METHYL-1 H-INDOL-5-YL)AMINO]NICOTINONITRILEStep a): Preparation of 5-formylbenzofuran.To a -150C to -2O0C solution of 1-benzofuran-5-carbonitrile (5 g, 34.9 mmol) in 50 mL of dichloromethane under nitrogen was added DIBAL-H (41.9 mL, 41.9 mmol, 1.0M in heptane) such that the temperature was less than or equal to -150C. The reaction mixture was stirred for an additional 10 min at -150C to -2O0C and quenched by adding 2.0 N HCI dropwise such that the temperature was less than or equal to room temperature. The organic layer was then separated, washed with water, dried over sodium sulfate and concentrated to give 4 g (78%) of the title compound as a yellow oil, which was used in the next step without further purification.

79002-39-4 Benzofuran-5-carbonitrile 2795184, abenzofuran compound, is more and more widely used in various fields.
