Procedure
To a suspension of compound 10f (100 mg, 0.29 mmol) in glacial acetic acid (2 mL) at room temperature was added nitric acid (0.1 mL, d 1.35) dropwise with vigorous stirring. The mixture was heated at 60° C. for 3 hr, allowed to cool for 30 min, and poured into cold water. The resulting precipitate was filtered, washed with water, and dried under high vacuum to afford compound SKC-BF-05 (45 mg, 42%) as an orange solid. TLC Rf=0.7 (CHCl3-MeOH, 9:1); 1H NMR (CDCl3) δ 7.89 (s, 1H), 7.85 (d, J=9.0 Hz, 2H), 6.95 (d, J=9.0 Hz, 2H), 3.89 (s, 3H); MS (ES) m/z 351 (M+H)+.
