反应详情

A solution of bromine (0.31 mL, 5.9 mmol) in carbon tetrachloride (10 mL) was added to a suspension of N-(4-acetylphenyl)acetamide (1 g, 5.6 mmol) (Lancaster Synthesis) in carbon tetrachloride (20 mL). The reaction mixture was stirred for several hours but TLC indicated only starting material. Acetic acid (10 mL) was added, and the reaction mixture was stirred overnight. Filtration gave N-[4-(bromoacetyl)phenyl]acetamide (1.4 g) as a solid. HPLC indicated that the purity was approximately 80%. This material was used directly in subsequent steps without purification.
