With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.22246-12-4,6-Methoxy-3,4-dihydroisoquinolin-1(2H)-one,as a common compound, the synthetic route is as follows.
To a solution of 6-methoxy-1-oxo-1,2,3,4-tetrahydroisoquinoline (31.3 g, 177 mmol) in CH2 Cl2 (300 mL) at -78 is added BBr3 (33.4 mL, 353 mmol). The reaction mixture is allowed to come to ambient temperature and is stirred for 12 hours. After this time the reaction mixture is cooled to 0 and is subsequently neutralized with 5N NaOH (150 mL) solution and saturated NaHCO3 solution. The resulting precipitate is extracted with hot acetone (4*500 mL) and the combined organics are concentrated in vacuo to give 6-hydroxy-1-oxo-1,2,3,4-tetrahydroisoquinoline.
The synthetic route of 22246-12-4 has been constantly updated, and we look forward to future research findings.
