The tetrahydroisoquinoline compound, cas is 215798-19-9 name is 6-Bromo-1,2,3,4-tetrahydroisoquinoline hydrochloride, mainly used in chemical industry, its synthesis route is as follows.
6-bromo- 1 ,2,3,4-tetrahydroisoquinoline hydrochloride (1. 5g, 6 mmol),and potassium carbonate (1.7g, 12 mmol) were taken in acetone (100 mL). 2,4,6- tnmethylbenzenesulfonyl chloride (1.6g, 7.2 mmol) was added to the reaction mixture andstirred at ambient temperature for 1 6h. Crude reaction mixture was concentrated under reduced pressure, extracted with saturated bicarbonate and brine, dried and concentrated. The crude mixture was purified on silica using ethyl acetate-hexane (3 0-70) to obtain the title compound (2.OOg, 85% yield). ?H NMR (400 MHz, DMSO-d6) oe ppm 2.27 – 2.29 (m, 3 H)2.54 (s, 6 H) 2.81 (t, J=6.00 Hz, 2 H) 3.39 (t, J=5.99 Hz, 2 H) 4.25 (s, 2 H) 7.09 (s, 3 H) 7.16(d, J8.31 Hz, 2 H) 7.33 – 7.36 (m, 2 H) 7.38 (m, J=2.00 Hz, 2 H). MS (m/z): 396.0, 397.0(M+H) for two bromine isomers., 215798-19-9
With the rapid development of chemical substances, we look forward to future research findings about 215798-19-9
