With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.34846-65-6,Isoquinoline-4-carbonitrile,as a common compound, the synthetic route is as follows.
To a stirred solution of isoquinolin-4-carbonitrile (Intermediate-13) (3.0 g, 19.45 mmol) in EtOH (30 mL) was added KOH (20 g in 20 mL water) and the mixture was refluxed overnight. It was then cooled to RT and concentrated under reduced pressure. The aqueous layer was washed with Et2O and neutralized using 1N HCl. It was extracted with EtOAc and the organic layer was dried over Na2SO4, filtered, and concentrated to give the title compound (2 g, 59.3percent) as an off white solid., 34846-65-6
As the paragraph descriping shows that 34846-65-6 is playing an increasingly important role.
