실험 절차
A solution of 2-iodophenylacetic acid (20.5 g, 78.2 mmol) in thionyl chloride (70 mL) was stirred at 75° C. for 3 hours. The thionyl chloride was removed in vacuo and the resulting residue was dissolved in DCM (100 mL). Ammonium carbonate (15.03 g, 156.5 mmol) was added and the resulting mixture was stirred at 60° C. for 20 hours. The volatiles were evaporated in vacuo, water (100 mL) was added and the resulting suspension was sonicated for 1 minute, before filtering and washing the filter cake with water then Et2O. After air drying, the title compound I6 was obtained as a light cream coloured solid (12.9 g, 63%); 1H NMR (300 MHz, d6-DMSO) δ 7.82 (d, J=8.3 Hz, 1H), 7.41 (brs s, 1H), 7.30-7.37 (m, 2H), 6.95-7.01 (m, 2H), 3.55 (s, 2H). LCMS-B: rt 5.108 min; m/z 262 [M+H]+.
