Analyzing the synthesis route of 569-31-3

As the paragraph descriping shows that 569-31-3 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.569-31-3,6,7-Dimethoxy-3H-1-isobenzofuranone,as a common compound, the synthetic route is as follows.

A solution of Compound 31a (6.31 g, 32.5 mmol) in acetonitrile (60 mL) was added NCS (4.77 g, 35.7 mmol) . After stirring at 60 C for 1 hour, the insoluble matter was collected by filtration, so as to yield compound 31b. Yield: 6.15 g, (83%) 1H-N R (CDC13) delta: 3.91 (3H,’s), 4.09 (3H, s) , 5.15 (2H, s), 7.16 (1H, s) .

As the paragraph descriping shows that 569-31-3 is playing an increasingly important role.
