240 °C

A mixture of 15 g (89 mmol) of m-methoxyphenyl acetic acid, 13.2 g (89 mmol) of phthalic anhydride and 246 mg (2.9 mmol) of sodium acetate was heated to 240° C. for 6 hours and water was continuously removed from the reaction. The solid formed in the reaction flask on cooling. This was recrystallized from absolute ethanol to obtain 15.6 g (62 mmol, 69%) of 1 as yellow powder.
