With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.887919-35-9,Bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II),as a common compound, the synthetic route is as follows.

Step 14-6, Preparation of tert-butyl N-{3-[(4-{4-[2-cyano-4-(trifluoromethyl)phenyl]piperazin-1-yl}-2′-ethoxy-[1,1′-biphenyl]-3-yl)formamido]propyl}carbamate To a mixture of tert-butyl N-{3-[(5-bromo-2-{4-[2-cyano-4-(trifluoromethyl)phenyl]piperazin-1-yl}phenyl)formamido]propyl}carbamate (20.0 mg, 0.0328 mmol), 2-ethoxyphenylboronic acid (10.9 mg, 0.0657 mmol), Pd[t-Bu2P(4-NMe2C6H4)]2Cl2) (9.2 mg, 0.013 mmol), and K2CO3 (27.2 mg, 0.197 mmol) in a sealed tube was added dioxane (2 mL) and H2O (0.2 mL). The resulting mixture was degassed with N2 for 10 min and stirred at 100 C. for 30 min. The mixture was concentrated and purified by C18 reversed phase column chromatography to give the title compound (18.5 mg, 87% yield) as a white solid. LCMS (M+H)+=652.5.
