552331-06-3,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.552331-06-3,6-Bromo-3-chloroisoquinoline,as a common compound, the synthetic route is as follows.
Step 2 To a mixture of 6-bromo-3-chloro-isoquinoline (XII) (0.5 g, 2.06 mmol), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1-(trideuteriomethyl)pyrazole (LXX) (1.305 g, 6.19 mmol) and SPhos Pd G4 (81.9 mg, 0.100 mmol) in 1,4-dioxane (10 mL) and was added a 2 M aqueous solution of K2CO3 (3.88 mL, 7.77 mmol). N2 gas was bubbled into the mixture for 10 min and then the mixture was heated to 110 C. for 0.5 h in a microwave. The organic layer was carefully separated, absorbed on silica gel and purified by column chromatography (0?100% hexanes/EtOAc) to obtain 3-chloro-6-[1-(trideuteriomethyl)pyrazol-4-yl]isoquinoline (LXXI) (400 mg, 1.62 mmol, 78.6% yield) as an off-white solid. ESIMS found for C13H7[2H3]ClN3 m/z 246.9 (M+1).
The synthetic route of 552331-06-3 has been constantly updated, and we look forward to future research findings.
