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
6-Bromoisoquinolin-3-amine: A mixture of 1,6-dibromoisoquinolin-3- amine (13.5 g, 45 mmol), ammonium formate (10.8 g, 172 mmol) and tetrakis(triphenylphosphine)palladium (0) (3.45 g, 3.0 mmol) in 50 mL of DMF was sealed in a 350 mL screw-cap flask and heated at 50 C for 48 h. To the reaction was added tetrakis(triphenylphosphine)palladium (0) (950 mg) and ammonium formate (3.0 g) and the mixture was heated at 50 C for 48 h. The mixture was cooled to room temperature and the solid was filtered, washed with a minimal amount of DMF, washed with Et2theta and dried in vacuo at 50 C to give the product as a yellow amorphous solid (10.4 g, 90 %) LCMS (API-ES) m/z: 222.9, 224.9 [M+ 1]. 1H NMR (300 MHz, DMSO- d6) delta ppm 8.81 (s, 1 H), 7.80 (d, J=I .6 Hz, 1 H), 7.73 (d, J=8.8 Hz, 1 H), 7.22 (dd, J=8.6, 1.9 Hz, 1 H), 6.55 (s, 1 H), 6.12 (s, 2 H).
As the paragraph descriping shows that 925672-85-1 is playing an increasingly important role.
