実験手順

Methanol (300 ml) was added in a single portion to 148 g (1.00 mole) of phthalic anhydride and the resulting suspension was stirred and heated at reflux for 36 hours; solution occurred during heating. The solvent was removed and the product was recrystallized from a mixture of ethyl acetate and hexane to afford 114.6 g of the title compound (Lit.: Beilstein, 9 797--m.p. 82.5°-84°).
