With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.226942-29-6,6-Bromo-1,2,3,4-tetrahydroisoquinoline,as a common compound, the synthetic route is as follows.
In a pressure vessel equipped with a magnetic stirring bar was added 6-bromo-l,2,3,4- tetrahydroisoquinoline (1.328 g, 6.26 mmol), and 2-chloro-4-(pyridin-3-yl)pyrimidine (1 g, 5.22 mmol) in acetonitrile (25 mL). Hunig’s base (2.73 mL, 15.66 mmol) was added and the mixture was heated to 80 C in a preheated oil bath and allowed to stir for 16 hours overnight. Reaction appears complete by LC/MS, cooled to RT and filtered solids, washed with ethyl acetate, concentrated in vacuo to a solid. Took up solid in EtOAc: heated to dissolve most material in minimum amount of solvent, filtered while hot, and allowed to cool to RT. After filtration and drying under vacuum, 1.5g (87%) of 6-bromo- 2-(4-(pyridin-3-yl)pyrimidin-2-yl)-l,2,3,4-tetrahydroisoquinoline was obtained as a light brown solid. LCMS (M+l) = 366.7 and 368.6., 226942-29-6
226942-29-6 6-Bromo-1,2,3,4-tetrahydroisoquinoline 15885183, atetrahydroisoquinoline compound, is more and more widely used in various fields.
