Chloroacetyl chloride → N-(4-bromo-2-nitrophenyl)-2-chloroacetamide

関与物質

反応手順

To a solution of 4-bromo-2-nitroaniline (15.0 g, 69.1 mmol) was added drop wise 2-chloroacetyl chloride (9.4 g, 82.9 mmol) under nitrogen. After refluxing for 1.5 h, the reaction mixture was cooled to ambient temperature and the solvent was removed under reduced pressure. Crystallization from ethyl acetate/hexane afforded N-(4-bromo-2-nitrophenyl)-2-chloroacetamide (19.4 g, 66.1 mmol, 96%) as yellow needles.
