Procedure

Compound of Example 15b (4.1 g, 12.8 mmol) was added to solution of nitrating mixture (nitric acid 200 mL and sulfuric acid 20 mL) at 0° C. and stirred for 18 h. The reaction mixture was poured slowly with stirring into ice water (200 mL). The solid separated was filtered, washed with water and dried to obtain the title compound. Yield: 2.5 g, (52%); 1H NMR (CDCl3, 300 MHz): δ 2.65 (s, 3H, CH3), 3.93 (s, 3H, OCH3), 4.57 (s, 2H, CH2), 8.16 (d, 2H, Ar), 8.35 (d, 2H, Ar); MS: m/e (ES−) 380 (M−1).
