Dimethylformamide → 2-(4-Bromophenoxy)acetamide

참여 물질

반응 단계

To a solution of (4-bromophenoxy)acetic acid (500 mg, 2.00 mmol) in dichloromethane (10 mL) and DMF (0.2 mL) was added 2 M oxalyl choride in methylene chloride (5 mL, 10 mmol). The reaction mixture was stirred at room temperature for 2 hours, and the solvent was removed under reduced pressure. Ammonium hydroxide (15 mL) was added dropwise via additional funnel. After addition, the mixture was extracted with EtOAc (3×20 mL). The combined organic layers were dried and concentrated in vacuo to give 2-(4-bromophenoxy)acetamide (350 mg, 70% yield) as a yellow solid. 1H NMR (400 MHz, CDCl3): δ 7.37-7.35 (m, 2 H), 6.81-6.79 (m, 2 H), 4.59 (s, 2 H).
