90% | With dicyclohexyl(2?,4?,6?-triisopropylbiphenyl-2-yl)phosphino-(2?-aminobiphenyl-2-yl)(chloro)palladium; sodium carbonate; In 1,4-dioxane; water; at 90.0℃; for 2.0h; | To a stirred solution of 6-bromo-2-(((tert-butyldimethylsilyl)oxy)(2, 6-difluorophenyl)methyl)-N,N-bis(4-methoxybenzyl)- [1 ,2,4 jtriazolo [1,5 -ajpyrazin-8-amine (1.37 g, 1.93 mmol) in 1,4-dioxane/H20 (4: 1, 13 mL), (3-cyano-2- fluorophenyl)boronic acid (0.413 g, 2.5 mmol), chloro(2-dicyclohexylphosphino- 2?,4?, 6?-triisopropyl- 1,1 ?-biphenyl) [2-(2 ?-amino- 1,1 ?-biphenyl)j palladium(II) (78 mg,0.1 mmol) (XPhos Pd G2) and sodium carbonate (0.613 mg, 5.78 mmol) were addedat rt. The reaction mixture was heated at 90 C for 2 hours. The reaction mixture was cooled to rt, extracted with dichloromethane and concentrated in vacuo. The residue was purified by Biotage Isolera eluting with 0 - 30% EtOAc/Hexane to give the product as a foamy solid (1.3 g, 90%). LCMS calculated for C41H42F3N6O3Si: mlz = 751.3, found 751.2. |
