With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1235865-77-6,2-((1H-Pyrrolo[2,3-b]pyridin-5-yl)oxy)-4-(4-((4′-chloro-5,5-dimethyl-3,4,5,6-tetrahydro-[1,1′-biphenyl]-2-yl)methyl)piperazin-1-yl)benzoic acid,as a common compound, the synthetic route is as follows.
4-(4-{[2-(4-chlorophenyl)-4,4-dimethylcyclohex-1-en-1-yl]methyl}piperazin-1-yl)-N-[(4-{[(cis-4-hydroxy-4-methylcyclohexyl)methyl]amino}-3-nitrophenyl)sulfonyl]-2-(1H-pyrrolo[2,3-b]pyridin-5-yloxy)benzamide A mixture of EXAMPLE 338J (144 mg), EXAMPLE 338M (95 mg), N,N-dimethylpyridin-4-amine (123 mg) and N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (62.7 mg) in dichloromethane (7 ml) was stirred overnight and concentrated. The residue was purified by reverse chromatography, eluted with 40%-70% acetonitrile in 0.1% TFA water. The desired fractions were concentrated, neutralized with NaHCO3 and extracted with dichloromethane. The organic layer was dried over Na2SO4, filtered, concentrated and dried to provide the title compound. 1H NMR (400 MHz, dimethylsulfoxide-d6) delta 11.69 (s, 1H), 11.38 (s, 1H), 8.59 (t, 1H), 8.55 (d, 1H), 8.04 (d, 1H), 7.79 (dd, 1H), 7.54 (d, 1H), 7.46-7.52 (m, 2H), 7.30-7.38 (m, 2H), 7.00-7.10 (m, 3H), 6.68 (dd, 1H), 6.39 (dd, 1H), 6.19 (d, 1H), 3.95 (s, 1H), 3.25 (t, 4H), 3.07 (s, 4H), 2.75 (s, 2H), 2.10-2.26 (m, 6H), 1.95 (s, 2H), 1.29-1.62 (m, 8H), 1.16-1.30 (m, 2H), 1.08 (s, 3H), 0.92 (s, 6H)., 1235865-77-6
