実験手順
This crude material was reacted with acetic acid (1.42 mL, 1.49 g, 24.8 mmol) and triethylamine (3.46 mL, 2.51 g, 24.8 mmol), as described above for the synthesis 10 of 3-(3,4-dichlorophenyl)propan-2-one. Flash chromatography over silica gel (20% ethyl acetate in hexanes) gave pure product (1.22 g, 46% yield): 1H NMR (400 MHz, CDCl3) δ 2.16 (s, 3H) 3.72 (s, 2H) 4.69-4.71 (m, 2H) 7.08-7.11 (m, 1H) 7.21-7.23 (m, 1H) 7.26-7.29 (m, 2H).
