Potassium Carbonate → 4-chloro-2-fluoro-5-methyl-N-phenoxycarbonylaniline

Participants

Reaction Steps

4-Chloro-2-fluoro-5-methylaniline (5 g, 31.4 mmol) was dissolved in tetrahydrofuran (100 ml) and potassium carbonate (6.0 g, 37.7 mmol) and phenyl chloroformate (5.9 g, 37.7 mmol) were added. Solution was refluxed for 3 hr and the solvent was removed under reduced pressure. Product was purified by column chromatography on silica gel (eluent, methylene chloride:hexane, 6:4; 7.15 g).
