Reaction Steps

To a stirred solution of 3-fluoro-4-(2-methoxyethoxy)aniline (2.0 g, 10.8 mmol, 1.0 eq) in acetone (50 mL) was added pyridine (2.5 mL, 32.4 mol, 3.0 eq.) and phenyl chloroformate (1.36 mL, 10.8 mmol, 1.0 eq.) at 0° C. and stirred at RT for 1 h. The solvent was evaporated, the residue diluted with EtOAc (50 mL), washed with water (100 mL), brine (20 mL) and evaporated again. The resulting residue was purified by column chromatography using EtOAc/PE (1:4) as eluent to yield phenyl 3-fluoro-4-(2-methoxyethoxy)phenylcarbamate (2.7 g, 76.8%) as a white solid (TLC system: EtOAc/PE (3:7), Rf: 0.5).
