Versuchsvorschrift

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 (10-30% ethyl acetate in hexanes) gave pure product (0.83 g, 33% yield). 1H NMR (400 MHz, DMSO-D6) δ ppm 2.08 (s, 3H) 3.80 (s, 2H) 4.85 (s, 2H) 7.17-7.36 (m, 5H).
