Procedure

A mixture of 4-bromo-1,8-naphthalic anhydride (10 g), aniline (3.54 g) and acetic acid (75 ml) was refluxed with stirring for 10 hrs. The reaction mixture was then cooled to room temperature, whereupon solid separated out. The solid was filtered, washed with water (50 ml) followed by acetic acid (50 ml) and dried at 100° C. for 8 hours (Yield=10.8 gm).
