With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.7169-34-8,Benzofuran-3(2H)-one,as a common compound, the synthetic route is as follows.,7169-34-8
General procedure: To a solution of benzofuran-3(2H)-one derivative (2a,b,d, 1.2 mmol) in ethanol (5 ml) in the presence of corresponding benzaldehyde (1.3 mmol), aqueous solution of 5% HCl (1 ml) was added and the mixture was refluxed for 6-9 hours (controlled by TLC). After cooling in an ice bath, the solution was neutralized by adding a cold solution of 2% KOH to reach the pH of 5-6. The resulting yellow precipitate was filtered and recrystallized from diluted methanol to give the desired products.
As the paragraph descriping shows that 7169-34-8 is playing an increasingly important role.
