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.
Example 1O 4-(4-{[2-(4-chlorophenyl)-4,4-dimethylcyclohex-1-en-1-yl]methyl}piperazin-1-yl)-N-[(4-{[(2R)-1,4-dioxan-2-ylmethyl]amino}-3-nitrophenyl)sulfonyl]-2-(1H-pyrrolo[2,3-b]pyridin-5-yloxy)benzamide EXAMPLE 1N (170 mg), EXAMPLE 1J (340 mg), 1-ethyl-3-[3-(dimethylamino)propyl]-carbodiimide hydrochloride (150 mg), and 4-dimethylaminopyridine (130 mg) were stirred in CH2Cl2 (5 mL) overnight. N1,N1-dimethylethane-1,2-diamine (0.19 mL) was then added and the mixture was stirred for 90 minutes. Dichloromethane (15 mL) was added, and the reaction mixture was washed with 10% acetic acid:0.75% NaCl in water (2*12 mL). The combined aqueous layers were back-extracted with dichloromethane, and the combined organics were washed with brine, and dried over Na2SO4. After filtration and concentration, the crude material was chromatographed on silica gel with 3/7 dichloromethane/ethyl acetate. The material was then chromatographed on silica gel with 1.5-2.5% CH3OH in dichloromethane. The material was triturated with CH3CN to afford the title compound. 1H NMR (400 MHz, dimethylsulfoxide-d6) delta ppm 11.65 (s, 1H), 8.55 (t, 1H), 8.54 (d, 1H), 8.01 (d, 1H), 7.81 (dd, 1H), 7.50 (m, 3H), 7.32 (d, 2H), 7.07 (d, 1H), 7.02 (d, 2H), 6.66 (dd, 1H), 6.37 (m, 1H), 6.18 (d, 1H), 3.77 (m, 3H), 3.63 (m, 2H), 3.47 (m, 2H), 3.31 (m, 2H), 3.06 (br m, 4H), 2.74 (br s, 2H), 2.19 (br m, 4H), 2.13 (br m, 2H), 1.94 (br m, 2H), 1.37 (t, 2H), 0.90 (s, 6H)., 1235865-77-6
