Procedure

The product from Example 21 (31 g) was dissolved in trifluoroacetic acid (450 mL). The solution was treated dropwise with 33 mL of fuming 90% nitric acid and stirred at room temperature. The reaction mixture was concentrated, the residue was dissolved in chloroform and then washed well with sodium bicarbonate solution. A solid formed, and was dissolved in 3 L chloroform and dried over magnesium sulfate. After evaporation, the residue was crystallized from ethyl acetate to give a white solid (19.32 g), and the filtrate concentrated to give an additional 16.3 g.
