0.75 g | With dichloro(1,1'-bis(diphenylphosphanyl)ferrocene)palladium(II)*CH2Cl2; caesium carbonate; In 1,4-dioxane; at 100.0℃; for 4.0h;Inert atmosphere; | To 2-((tert-butoxycarbonyl)amino)-2-(4-bromophenyl)acetate 1 g (2.91 mmol) was added <strong>[4540-87-8](2-(((benzyloxy)carbonyl)amino)ethyl)boronic acid</strong> 0.97 g (4.36 mmol, 1.5 eq), cesium carbonate 2.84 g (8.72 mmol, 3 eq), Pd(dppf)Cl . 2dichloromethane 0.24 g (0.29 mmol, 0.1 eq), followed by dioxane (19 mL) and degassed 3X under an atmosphere of argon. The reaction mixture was heated at 100 oC for 4 h, cooled at RT, diluted with dichloromethane, filtered through Celite, washed with water/brine, dried over sodium sulfate and concentrated. The crude product was purified by flash chromatography on silica gel (30% ethyl acetate/hexanes) to afford the title compound, 0.75 g. ESI- MS m/z 443 (M+H)+. |
