Procedure

To a solution of compound 7 (259 mg, 1.0 mmol) and triethylamine (0.5 mL) in dry CH2Cl2 (20 mL) was added a solution of 2-bromo-4-nitrobenzoic acid chloride in 20 mL of CH2Cl2 (which was prepared by refluxing of 295 mg, 1.2 mmol of 2-bromo-4-nitrobenzoic acid in 10 mL of thionyl chloride for 4 h). The reaction mixture was heated to reflux for 6 h. The reaction mixture was allowed to cool and was then washed with saturated NaHCO3 solution, water and brine and dried over anhydrous Na2SO4. The solvent was then removed in vacuo to give a yellow solid; yield 345 mg (70.8%); mp 111–112° C.; 1H NMR (CDCl3) δ (2.29, S, 6H), 2.60 (t, 2H, J=6.2), 3.62–3.72 (m, 1H), 4.49–4.62 (m, 1H), 6.19 (d, 2H, J=5.6), 7.12 (d, 1H, J=8.2), 7.37 (s, 3H), 7.75 (d, 1H, J=8) 8.26 (s, 1H), 8.5 (d, 1H, J=4.6); 13C NMR(CDCl3) δ 45.4, 46.6, 56.4, 97.8, 102.4, 106.7, 119.5, 120.6, 121.7, 122.7, 127.6, 128.1, 143.6, 144.4, 147.9, 148.2, 148.5, 149.5, 151.4, 166.8.
