With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.17680-55-6,7-Bromo-1,2,3,4-tetrahydroisoquinoline,as a common compound, the synthetic route is as follows.,17680-55-6
EXAMPLE 105; To a solution of Intermediate 21 (150 mg, 0.43 mmol) in dichloromethane (10 mL) was added EDC (170 mg, 0.86 mmol), HOAt (59 mg, 0.43 mmol) and Intermediate 21 (91 mg, 0.43 mmol) and the resulting mixture was stirred at room temperature for 3 days. The reaction was quenched with water and diluted with 20 mL of dichloromethane. The organic layer was separated and the aqueous layer was extracted with DCM (2¡Á20 mL). The organics were combined, dried over sodium sulfate, filtered and evaporated under reduced pressure. The residue was purified by preparative TLC (eluant: 7% ethanol: 92% dichloromethane: 1.0% NH4OH) to yield 121 mg (50%) of the final desired product as a mixture of two cis isomers. LC-MS for C29H36BrFN2O calculated 526.28, found [M+H]+ 527 and [(M+2)+H]+ 529.
17680-55-6 7-Bromo-1,2,3,4-tetrahydroisoquinoline 10729255, atetrahydroisoquinoline compound, is more and more widely used in various fields.
