실험 절차

Methyl bromoacetate (1.95 mL, 20 mmol) is added dropwise to a solution of 2-cyanophenol (2.38 g, 20 mmol), and K2CO3 (2.78 g, 20.1 mmol) in acetone (100 mL) stirred under N2 at 25° C. After 24 h, the solid is filtered off and the filtrate is concentrated in vacuo and the residue is dried in a vacuum oven to give methyl 2-(2-cyanophenoxy)ethanoate (3.82 g, 100%) as a beige solid. 1H NMR (DMSO) δ7.76 (1H, dd, J=7.6, 1.7 Hz), 7.64 (1H, dt, Jd=1.6 Hz, Jt=8.0 Hz), 7.20˜7.10 (2H, m), 5.04 (2H, brs), 3.70 (3H, s).
