With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.81237-69-6,5-Bromo-1,2,3,4-tetrahydroisoquinoline,as a common compound, the synthetic route is as follows.
Example 5f 5-bromo-2-(2-(methylsulfonyl)ethyl)-1,2,3,4-tetrahydroisoquinoline A mixture containing 5-bromo-1,2,3,4-tetrahydroisoquinoline (212 mg, 1 mmol) and methylsulfonylethene (106 mg, 1 mmol) in dichloromethane is stirred at 35 C. for 14 hours. The solution is concentrated to afford 5-bromo-2-(2-(methylsulfonyl)ethyl)-1,2,3,4-tetrahydroisoquinoline as a brown oil (LC-MS m/z: 318.1 (M+1)) which is used without further purification in the next step.
81237-69-6 5-Bromo-1,2,3,4-tetrahydroisoquinoline 12823199, atetrahydroisoquinoline compound, is more and more widely used in various.
