Procedure
The procedure described above for the synthesis of 3-(3,4-dichlorophenyl)-2-oxopropyl acetate was followed, reacting 1-chloro-3-(2-chlorophenyl)propan-2-one (0.556 g, 2.74 mmol) with acetic acid (0.31 mL, 0.33 g, 5.5 mmol) and triethylamine (0.76 mL, 0.56 g, 5.5 mmol). Flash chromatography over silica gel (5-40% ethyl acetate in hexanes) gave pure product (0.251 g, 43% yield): 1H NMR (400 MHz, CDCl3) δ 2.17 (s, 3H) 3.88 (s, 2H) 4.75 (s, 2H) 7.24-7.27 (m, 3H) 7.38-7.42 (m, 1H).
