실험 절차

To a stirred solution of ethyl 1-(4-amino-3-(2,2,2-trifluoroethoxy)phenyl)cyclopentanecarboxylate (1.2 g, 3.6 mmol) in dry CHCl3 (60 mL), NCS (0.411 g, 3.08 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 1-(4-amino-3-chloro-5-(2,2,2-trifluoroethoxy)phenyl)cyclopentanecarboxylate (0.860 g) as a thick syrup.
