実験手順

To a stirred solution of ethyl 2-(4-amino-3-(2,2,2-trifluoroethoxy)phenyl)-4-methylpentanoate (0.25 g, 0.75 mmol) in dry CHCl3 (20 mL), NCS (0.08 g, 0.6 mmol) was added at 0° C. The reaction mixture was allowed to stir for 3 at room temperature to complete the reaction. The reaction mixture was diluted with water, extracted with DCM (2×100 mL), the combined organic solvents was dried over Na2SO4, filtered and concentrated in vacuo. The crude reaction mixture was purified by Flash column chromatography to yield ethyl 2-(4-amino-3-chloro-5-(2,2,2-trifluoroethoxy)phenyl)-4-methylpentanoate (0.15 g) as thick syrup.
