Sodium Acetate → 2-Oxo-2-(3-(quinoxalin-2-yl)phenylamino)ethyl acetate

Participants

Reaction Steps

A solution of 2-bromo-N-(3-(quinoxalin-2-yl)phenyl)acetamide (100 mg, 0.292 mmol) and sodium acetate (159 mg, 1.168 mmol) in acetonitrile (5 mL) was heated in microwave at 140° C. for 7.5 min. The dark-yellow solution was diluted with ethyl acetate (25 mL), washed with water (20 mL), dried over sodium sulphate and the solvent evaporated to afford 2-oxo-2-(3-(quinoxalin-2-yl)phenylamino)ethyl acetate (70 mg, 74% yield). LCMS calculated for C18H15N3O3 (M+H): 322.33. found 322. 1H-NMR (DMSO-d6, 400 Mhz) δH: 10.3 (1H, br.), 9.51 (1H, s), 8.52 (1H, m), 8.15-8.20 (2H, m), 8.08-8.10 (1H, m), 7.82-8.00 (3H, m), 7.55-7.60 (1H, m), 4.70 (2H, s), 2.15 (3H, s).
