6-Bromo-1,2,3,4-tetrahydroisoquinoline, cas is 226942-29-6, it is a common heterocyclic compound, the tetrahydroisoquinoline compound, its synthesis route is as follows.
To a solution of 6-bromo-1,2,3,4-tetrahydroisoquinoline (0.700 g, 3.30 mmol) in DCM (30 mL) was added Intermediate 1-13 (0.640 g, 3.63 mmol) followed by sodium triacetoxyborohydride (1.40 g, 6.60 mmol). The resulting reaction mixture was stirred at ambient temperature for 14 h. The reaction mixture was diluted by water (50 mL) and extracted with DCM (2 x 50 mL). The combined extracts were washed with brine (50mL), dried over anhydrous sodium sulfate and concentrated. The crude was washed withdiethyl ether (2 x 50 mL) to afford Intermediate 6A (1.05 g, 73.5 %) as a brown solid. ?HNIVIR (400 MHz, DMSO-d6) ppm 2.70-2.80 (m, 6 H), 2.99 (t, J= 10 Hz, 2 H), 3.59 (s, 2H), 5.37 (s, 2 H), 7.03 (d, J= 10.8 Hz, 1 H), 7.27 (d, J= 2.4 Hz, 1 H), 7.31 (s, 1 H), 7.50(d, J= 10.4 Hz, 1 H), 7.56 (s, 1 H), 7.76 (d, J= 10.4 Hz, 1 H). LCMS (MethodR):retention time 1.03 mi (M+H) 374.2.
With the rapid development of chemical substances, we look forward to future research findings about 226942-29-6
