4-Methylmorpholine → 2-(4-bromophenoxy)-N-methylacetamide

To a solution of (4-bromophenoxy)acetic acid (500 mg, 2.10 mmol) in N,N-dimethylformamide (15 mL) was added methylamine hydrochloride (320 mg, 5.10 mmol), (1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (570 mg, 3.00 mmol), 1-hydroxybenzotriazole (400 mg, 3.00 mmol) and N-methyl-morpholine (600 mg, 6.00 mmol). The mixture was stirred at room temperature overnight. The reaction was quenched with water (20 mL), and then washed three times with ethyl acetate (20 mL). The combined organics was dried and concentrated to give the title compound (580 mg, 90% yield) that was used without further purification. 1H NMR (400 MHz, CDCl3) δ 7.45 (d, 2H), 6.79 (d, 2H), 6.56 (s, 1H), 4.46 (s, 2H), 2.91 (d, 3H).
