反応手順
A mixture of tetrachlorophthalic anhydride (2.97 g, 0.010 mole), 1-methylethyl 5-amino-2-chlorobenzoate (2.22 g, 0.010 mole) and toluene (100 ml) was heated slowly to reflux with stirring, then left overnight at room temperature. Filtration of the reaction mixture gave the title compound, m.p. 178°-179° C. (3.45 g, 70% yield).
