実験手順

To a stirred solution of ethyl 2-(4-amino-3-(cyclopropylmethoxy)phenyl)acetate (1.2 g, 4.0 mmol) in dry CCl4 (60 mL), NCS (0.427 g, 3.2 mmol) was added at 0° C. The reaction mixture was allowed to stir for 3 h at room temperature. The reaction mixture was diluted with water and extracted with DCM (2×50 mL). The combined organic layers were dried over Na2SO4, filtered and the volatiles removed in vacuo. The crude reaction mixture was purified by column chromatography to give ethyl 2-(4-amino-3-chloro-5-(cyclopropylmethoxy)phenyl)acetate (920 mg) as a yellow solid.
