실험 절차

A mixture of methyl 3-chloro-4-fluoro-α-azidocinnamate (Japanese Patent Application Laid-Open No. 149723/1995) (1.85 g) and xylene (140 ml) was heated under reflux for 1 hour, and the solvent was then distilled off. The residue was purified by column chromatography on silica gel (methylene chloride) to obtain the title compound (491 mg).
