1059630-07-7, (4aS,9bR)-6-Bromo-2,3,4,4a,5,9b-hexahydro-1H-pyrido[4,3-b]indole is a indole-building-block compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
(4aS,9bR)-ethyl 6-bromo-3,4,4a,5-tetrahydro-lH-pyrido[4,3-b]indole- 2(9bH)-carboxylate may be prepared by first obtaining [4aS, 9bR]-6-bromo- 2,3,4,4a,5,9b-hexahydro-17/-pyrido[4,3-h]indole (36.0 g, 0.142mol)) as a free base by using 50% aqueous sodium hydroxide solution and extracting the product into MTBE. The conversion to (4aS,9bR)-ethyl 6-bromo-3,4,4a,5-tetrahydro-lH-pyrido[4,3- b]indole-2(9bH)-carboxylate may then be done by cooling a suspension of [4aS, 9bR]- 6-bromo-2,3,4,4a,5,9b-hexahydro-17/-pyrido[4,3-h]indole (36.0 g, 0.142mol)) in THF (300 ml) and triethylamine (24 ml) in an ice-water bath. Ethyl chloroformate is added dropwise (13.5 ml, O.l42mol) via a syringe pump over 1 hour. The ice-water bath is removed and the reaction mixture is stirred at room temperature for another hour. The reaction mixture is passed through a pad of Celite and the solvent is evaporated to give (4aS,9bR) -ethyl 6-bromo-3,4,4a,5-tetrahydro-lH-pyrido[4,3-b]indole-2(9bH)- carboxylate). 1H NMR (CDCb, 300 MHz): 1.20-1.35 (m,3H), 1.73-1.85 (m, 1H), 1.85-1.99 (m, 1H), 3.22-3.52 (m, 3H), 3.52-3.66 (m, 1H), 3.66-3.95 (Br, 1H), 3.95-4.21 (m, 4H), 6.60 (t, J = 7.7 Hz, 1H), 7.04 (d, J = 7.2 Hz, 1H), 7.20 (d, J = 8.1 Hz, 1H).
1059630-07-7, The synthetic route of 1059630-07-7 has been constantly updated, and we look forward to future research findings.
