To a stirred solution of (4-amino-2-fluorophenyl)methanol (100 mg, 0.709 mmol, 1 eq.) in acetone (1.0 mL) was added pyridine (0.17 mL, 2.12 mmol, 3 eq.) followed by phenyl chloroformate (0.092 mL, 0.709 mmol, 1 eq.) at 0° C. and stirred at RT for 1 h. The solvent was evaporated and the residue obtained was purified by CC using ethyl acetate/PE (7:13) as eluent to get phenyl 3-fluoro-4-(hydroxymethyl)phenylcarbamate (110 mg, 60%, off-white solid; TLC system: EtOAc/PE (1:1), Rf: 0.4).
