With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.81868-12-4,2-(5-Bromo-1H-indol-3-yl)ethanamine hydrochloride,as a common compound, the synthetic route is as follows.

81868-12-4, A stirred suspension of 5-bromotryptamine hydrochloride (17.0 g, 61.7 mmol) in 250 mL of 0.1 N aqueous sulfuric acid was treated with isovaleraldehyde (10.0 mL, 92.6 mmol). The suspension was heated at 80 C. for 3 hr. The resulting solution was allowed to cool to ambient temperature then further cooled to 0 C. in an ice-water bath. The precipitated product was filtered, washed with MTBE (300 mL), dried overnight under high vacuum to give 6-bromo-1-isobutyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole hydrochloride 19.3 g (92%) as a white solid. 1H NMR (600 MHz, DMSO-d6) delta 11.41 (s, 1H), 9.92 (br. s., 1H), 9.46 (br. s., 1H), 7.66 (d, J=1.88 Hz, 1H), 7.33 (d, J=8.56 Hz, 1H), 7.21 (dd, J=1.88, 8.56 Hz, 1H), 4.66 (br. s., 1H), 3.54 (d, J=12.14 Hz, 1H), 3.27 (br. s., 1H), 2.86-3.01 (m, 2H), 2.01-2.09 (m, 1H), 1.91-1.99 (m, 1H), 1.83 (ddd, J=4.09, 10.23, 14.28 Hz, 1H), 1.03 (d, J=6.31 Hz, 3H), 0.97 (d, J=6.59 Hz, 3H).

Brief introduction of 81868-12-4

The synthetic route of 81868-12-4 has been constantly updated, and we look forward to future research findings.

81868-12-4, 2-(5-Bromo-1H-indol-3-yl)ethanamine hydrochloride is a indole-building-block compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,81868-12-4

A solution of 4-((3-fluorophenyl)(methyl)amino)benzoic acid (0.250 g, 1.09 mmol), 2-(5-bromo-1H-indol-3-yl)ethanamine hydrochloride (0.300 g; 1.09 mmol), HATU (0.414 g; 1.09 mmol) and N,N-diisopropylethylamine (0.469 mL; 2.72 mmol) in DMF (7 mL), was stirred at room temperature for 72 hours. The reaction mixture was then partitioned between ethyl acetate and sodium hydrogen sulfate and the organic layer was successively washed with a saturated aqueous solution of sodium carbonate and brine. The organic layer was dried, concentrated under reduced pressure and the crude material was purified by flash chromatography on silica gel (eluent 1 to 20% ethyl acetate in dichloromethane) to afford 0.395 g (81%) of the title compound as a white solid. [0652] ESI/APCI(+): 451, 453 (M+H); 473,475 (M+Na); ESI/APCI(-): 450, 451 (M-H).
