Chloroacetyl chloride → 2-chloro-N-(3,4,5-trimethoxyphenyl)acetamide

Participants

Reaction Steps

3,4,5-Trimethoxyaniline (Aldrich, 4.06 g, 22.2 mmol) and chloroacetyl chloride (2.60 mL, 32.7 mmol) in toluene (50 mL) were heated at 100° C. for 24 hours. The mixture was allowed to cool to room temperature and the volatiles were removed under reduced pressure. The residue was taken up in toluene and concentrated (3×) to remove traces of starting acid chloride and placed under high vacuum to provide 5.26 g (91%) of the title compound as a light brown solid. 1H NMR (500 MHz, DMSO-d6) δ 3.62 (s, 3H), 3.74 (s, 6H), 4.21 (s, 2H), 6.96 (s, 2H), 10.19 (br s, 1H); MS (DCI/NH3) m/e 260 (M+H)+.
