As a common heterocyclic compound, it belongs to tetrahydroisoquinoline compound, name is 6-Bromo-1,2,3,4-tetrahydroisoquinoline hydrochloride, and cas is 215798-19-9, its synthesis route is as follows.,215798-19-9
Step F: Preparation of l-(6-Bromo-3,4-dihydroisoquinolin-2(lH)-yl)ethanone. To a stirred slurry of 6-bromo-l,2,3,4-tetrahydroisoquinoline hydrochloride (2.460 g, 9.90 mmol) in THF (39.6 mL) was added triethylamine (4.14 mL, 29.7 mmol). The reaction mixture was cooled in an ice-bath, and acetyl chloride (0.880 mL, 12.37 mmol) was added slowly. The ice-bath was removed and the mixture was stirred at room temperature for 30 min. The mixture was diluted with ethyl acetate and washed with 1 M HCl and brine. The ethyl acetate layer was dried over sodium sulfate and the solvent was removed under reduced pressure. The residue was purified by silica gel column chromatography to give the title compound (1.983 g). LCMS m/z = 256.3 [M+H]+. 1H NMR (400 MHz, CDCl3) delta ppm 2.17 (d, J = 1.52 Hz, 3H), 2.78-2.91 (m, 2H), 3.60-3.86 (m, 2H), 4.53-4.70 (m, 2H), 6.94-7.06 (m, IH), 7.28-7.36 (m, 2 H).
With the complex challenges of chemical substances, we look forward to future research findings about 6-Bromo-1,2,3,4-tetrahydroisoquinoline hydrochloride
