4-Bromoaniline (10m CAS# 106-40-1) 6 Br -NH₂ (243 mg, 1.0 General procedure A was followed with 2-(4-bromophenoxy)propanamide mmol), KOH (112 mg, 2.0 mmol) and DMSO (4 mL) was stirred at 140 °C for 3 h. The product was purified by flash column chromatography (petroleum ether/ethyl acetate 10:1) as a white solid (147 mg, 86 %). ¹H NMR (400 MHz, CDC13): 8 7.23 (d, 2H, J = 8.4 Hz), 6.55 (d, 2H, J = 8.4 Hz), 3.64 (br s, 2H); ¹³C NMR (100 MHz, CDC13): 8 145.4, 131.9, 116.7, 110.2. ESI-MS: m/z = 172 (M+H).
