Procedure

1.98 g (10.0 mmol) of 1,8-naphthalenedicarboxylic anhydride and 0.985 g (5.00 mmol) of hydroxylammonium phosphate were reacted with 2 ml of water analogously to Example 7 for 6 hours at a bath temperature of 130° C. Following cooling, the pale brown reaction mixture was digested with water, and the solid was filtered off with suction and dried. The yield was 1.89 g (89%).
