実験手順
A mixture of 0.5 g (0.0016 mole) of N-(4-chloro-2-fluoro-5-hydroxymethylphenyl]-3,4,5,6-tetrahydrophthalimide, 0.66 g (0.0055 mole) of phenyl isocyanate, 0.73 g (0.0072 mole) of triethylamine, and 25 ml of methylene was stirred at room temperature overnight. Sufficient methanol was added to react with the excess phenyl isocyanate, and the reaction mixture was stirred for an additional 24 hours. The reaction mixture was diluted with ethyl acetate and was washed successively with water and 5% hydrochloric acid. The organic phase was dried, filtered, and the solvent was evaporated under reduced pressure. The residue was passed through a column of silica gel. The appropriate fractions were combined, and the solvent was evaporated under reduced pressure, leaving a white solid as a residue. This solid was recrystallized from ethyl acetate/heptane, yielding 0.29 g of N-[4-chloro-2-fluoro-5-(phenylaminocarbonyloxy)phenyl]-3,4,5,6-tetrahydrophthalimide as a white solid, m.p. 149°-151° C. The nmr and ir spectra were consistent with the proposed structure.
