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.
(0413) To a solution of Compound 3J (90 mg), Compound 130C (64.2 mg), triethylamine (0.077 ml), N,N-dimethylpyridin-4-amine (38.5 mg) in a mixture of dichloromethane (5 ml) and N,N-dimethylformamide (0.5 ml) was added N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine, hydrochloric acid (60.4 mg) and the mixture was stirred 18 hours. This was concentrated on high vacuum and the crude was purified by reverse phase chromatography with ammonium acetate buffer/acetonitrile. 1H NMR (500 MHz, pyridine-d5) delta 13.03 (s, 1H), 9.27 (d, 1H), 8.59 (d, 1H), 8.43 (d, 1H), 8.37 (dd, 1H), 8.11 (d, 1H), 7.65-7.67 (m, 2H), 7.44 (d, 2H), 7.07 (d, 2H), 6.88 (d, 1H), 6.76 (dd, 1H), 6.54 (d, 1H), 6.48 (m, 1H), 4.06 (m, 1H), 3.98 (d, 2H), 3.35 (t, 2H), 3.07 (m, 4H), 2.73-2.80 (m, 4H), 2.68-2.72 (m, 1H), 2.36 (q, 1H), 2.11-2.30 (m, 9H), 1.97 (m, 2H), 1.62-1.71 (m, 3H), 1.48-1.58 (m, 2H), 1.39 (t, 2H), 0.94 (s, 6H)., 1235865-77-6
