Procedure
Fuming HNO3 (500 mL) was cooled to 10-15° C. and the compound of Example 1 (80 g, 1 eq.) was added in portions over a period of 20 min. The reaction mixture was heated to 67° C. for 4 h. The mixture was cooled to 20° C. and added to ice (2 kg) with stirring. The yellow suspension was filtered and the product was washed with water (1500 mL). After drying, a yellow solid (70 g; 70% yield) was obtained.
