In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 175867-59-1 as follows. Product Details of 175867-59-1
((R)-4-(5-(4-chlorophenyl)-1-ethyl-4-(3-(4-(4-(4-(4-(4-hydroxypiperidin-1-yl)-1-(phenylthio)butan-2-ylamino)-3-(trifluoromethylsulfonyl)phenylsulfonamido)phenyl)piperazin-1-yl)phenyl)-2-methyl-1H-pyrrole-3-carboxamido)cyclohexanecarboxylic acid (10) To a solution of BM-957 (100 mg, 0.09 mmol), EDCI (27 mg, 0.14 mmol) and HOBT (19 mg, 0.14 mmol) in DCM (2 mL) was added methyl 4-aminocyclohexanecarboxylate (44 mg, 0.28 mmol). The solution was stirred for 2 hours at room temperature until no BM-957 was observed by TLC. The reaction mixture was diluted with ethyl acetate (50 mL), washed with saturated NaHCO3 solution (50 mL), brine (50 mL) and dried over sodium sulfate. The solvent was removed in vacuo to give crude product which was used for next step without purification. The resulting residue was dissolved in H2O and MeOH (5 mL and 5 mL respectively) and followed by adding NaOH (76 mg, 1.9 mmol). The solution was stirred at room temperature for 20 h until no starting material was observed by TLC. The reaction mixture was concentrated in vacuo and the residue was purified by HPLC to give the pure product 10 (salt with TFA, 61 mg, yield 55% over two steps). The gradient ran from 60% of solvent A and 40% of solvent B to 20% of solvent A and 80% of solvent B in 40 min. MS (ESI): m/z 1191.17 (M+H)+.
According to the analysis of related databases, 175867-59-1, the application of this compound in the production field has become more and more popular.
