Acetic Acid → 3-(3-Chlorophenyl)-2-oxopropyl Acetate

Participants

Reaction Steps

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 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).
