With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.925672-85-1,1,6-Dibromoisoquinolin-3-amine,as a common compound, the synthetic route is as follows.,925672-85-1
Preparation of intermediate 6-bromoisoquinolin-1-d-3-amine (XI) is depicted below in Scheme 4. RRN 12Step 1 (0813) To a mixture of 13 1,6-dibromoisoquinolin-3-amine (X) (0.5 g, 1.66 mmol), 14 ammonium formate-d5 (0.56 g, 8.28 mmol) and 15 Pd(PPh3)4 (191.3 mg, 0.170 mmol) in 16 DMF (5 mL) was heated to 50 C. for 48 h. The solvents were concentrated and the residue was suspended in 17 chloroform. The solid was collected by filtration and washed with water and EtOAc. The solid were dried under high vacuo to obtain 18 6-bromo-1-deuterio-isoquinolin-3-amine (XI) (115 mg, 0.513 mmol, 31.0% yield) as a pale yellow solid. 1H NMR (500 MHz, DMSO-d6) delta ppm 6.11 (2H, s), 6.55 (1H, s), 7.22 (1H, dd, J=8.78, 1.92 Hz), 7.73 (1H, d, J=8.51 Hz), 7.79 (1H, d, J=1.92 Hz); ESIMS found for C9H6DBrN2 m/z 224.0 (79BrM+H).
925672-85-1 1,6-Dibromoisoquinolin-3-amine 16049917, aisoquinoline compound, is more and more widely used in various fields.
