YieldReaction ConditionsOperation in experiment
81% Stage #1: 2‐(2‐chlorophenyl)aniline With n-butyllithium In tetrahydrofuran; hexane at 0℃; for 0.5h; Inert atmosphere; Schlenk technique; Sealed tube; Stage #2: chlorodicyclohexylphosphane In tetrahydrofuran; hexane at 20℃; for 48h; Inert atmosphere; Schlenk technique; Sealed tube; Synthesis of N-PR2 protected anilines 35-39a General procedure: To a solution of 2'-chloro-[1,1'-biphenyl]-2-amine S-1 (2 mmol) in 7 mL anhydrous THF at 0 °Cwas added a solution of n-BuLi (2.4 mmol, 2.5 M in hexane) dropwise. After stirring for 0.5 h, R2PCl(2.2 mmol) was added dropwise. The mixture was allowed to stir and warm to room temperature over48 h. After aniline was consumed determined by TLC, the reaction was quenched by 2 mL MeOH.Then the solvent was removed under reduced pressure. N-PR2 protect aniline were obtained by furtherpurification through flash chromatography.

After stirring for 0.5 h, R1R2PCl[4-6] (2.2 mmol) was addeddropwise. The mixture was allowed to stir and warm to room temperature over 48 h. After aniline wasconsumed determined by TLC, the reaction was quenched by 2 mL MeOH. Then the solvent wasremoved under reduced pressure. N-PR1R2 protect anilines were obtained by further purificationthrough flash chromatography. To a solution of A in anhydrous THF at 0 °C was added a solution ofborane dimethylsulfide complex (2 mmol) dropwise. After stirring for 0.5 h, the reaction mixture wasquenched with water at 0 °C and extracted with EtOAc. The mixture was purified by chromatographyto give N-PR1R2 protect anilines broane.
