PROCEDURE

实验过程

To a stirred solution of (R)-1-(4-chloro-3-(1-(2,4-dichlorophenyl)ethylamino)phenyl)piperidin-4-one (0.13 g, 0.32 mmol) and 3-(t-butoxycarbonylamino)pyrrolidine (0.24 g, 1.3 mmol) in dichloroethane (DCE) (2 mL) was added NaBH(OAc)3 (0.094 g, 0.44 mmol). The reaction mixture was heated at 80° C. for 4 h. The reaction mixture was quenched with aqueous saturated sodium bicarbonate and extracted with dichloromethane. The organic layer was dried (Na2SO4), filtered, and concentrated in vacuo. The resulting crude was purified by flash chromatography (SiO2, 1-7% methanol in dichloromethane) to give t-butyl 1-(1-(4-chloro-3-((R)-1-(2,4-dichlorophenyl)ethylamino)phenyl)piperidin-4-yl)pyrrolidin-3-ylcarbamate (0.092 g, 0.16 mmol, 31%).
