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 2M oxalyl chloride 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, 2H), 6.81-6.79 (m, 2H), 4.59 (s, 2H).
