With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1423-61-6,7-Bromobenzo[b]thiophene,as a common compound, the synthetic route is as follows.
Scheme I, step C: 7-bromobenzo(b)thiophene (3.01 g, 14.1 mmol, prepared above in step B) is dissolved in diethyl ether (20 mL) and the solution is added dropwise to a suspension of magnesium (0.69 g, 28.3 mmol) in diethyl ether (20 mL). Dibromoethane (1.22 mL, 14.1 mmol) in diethyl ether (10 mL) is then added dropwise to the reaction mixture, which is then heated to reflux for 3 hours. The reaction is then cooled to room temperature and 1-(t-butoxycarbonyl)-3-pyrrolidone (14.1 mmol, prepared following the procedure described in Synlett., 1, 55-57 (1995)) is added. The reaction is stirred overnight at room temperature. Water is then added to the reaction, and the mixture is extracted with diethyl ether. The organic layers are combined, dried over anhydrous sodium sulfate, filtered and concentrated under vacuum. The residue is purified by flash chromatography (hexane:ethyl acetate, 7:3, silica gel) to provide 1-(t-butoxycarbonyl)-3-(7-benzo(b)thiophene)-3-hydroxy pyrrolidine.
1423-61-6, The synthetic route of 1423-61-6 has been constantly updated, and we look forward to future research findings.
