With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.82771-60-6,7-Chloro-1,2,3,4-tetrahydroisoquinoline,as a common compound, the synthetic route is as follows.,82771-60-6
To a mixture of 7-chloro- l,2,3,4-tetrahydroisoquinoline (200 mg, 1.19 mmol), 5-bromo-2- pyrimidin-2-yl-pyrimidine (226 mg, 954 muiotaetaomicron, the product of step 3 in Example 1) and CS2CO3 (1.94 g, 5.97 mmol) in dioxane (15 mL) was added Brettphos Pd G3 (216 mg, 239 muiotaetaomicron, CAS registry number: 1470372-59-8). The resulting mixture was heated at 120 C with stirring for 48 hrs under N2 and filtered. The filtrate was concentrated in vacuo. The residue was purified by prep-HPLC to give 7-chloro-2-(2-pyrimidin-2-ylpyrimidin-5-yl)-3,4-dihydro- lH-isoquinoline (0436) (26 mg) as light yellow solid. XH NMR (400 MHz, Methanol-^) delta ppm: 8.87-8.99 (m, 2H), 8.55- 8.70 (m, 2H), 7.45-7.59 (m, IH), 7.25-7.38 (m, IH), 7.21 (s, 2H), 4.62 (s, 2H), 3.76 (t, 2H), 3.02 (s, 2H). MS obsd. (ESI+) [(M+H)+] : 324
The synthetic route of 82771-60-6 has been constantly updated, and we look forward to future research findings.
