Reaction Steps

To a solution of (3-quinoxalin-2-ylphenyl)amine (200 mg, 0.904 mol) and glycolic acid (83 mg, 1.085 mmol) in dry DMF (6 mL), EDC (191 mg, 1 mmol) and HOBt hydrate (154 mg, 1 mmol) were added and the reaction mixture was heated at 60° C. for 18 hrs. The solvent was evaporated in vacuo (45° C., 0.1 mbar) and the residue was dissolved in ethyl acetate (50 mL) and washed with water (2×25 mL). The organic phase was washed dried over sodium sulphate, filtered, the solvent evaporated in vacuo, the residue was triturated with DCM and further purified by preparative LCMS to afford 2-hydroxy-N-(3-(quinoxalin-2-yl)phenyl)acetamide (60 mg, 23% yield). LCMS calculated for C16H13N3O2 (M+H): 280.29. found 280. 1H-NMR (DMSO-d6, 400 Mhz) δH: 10.38 (1H, br.), 9.52 (1H, s), 8.62 (1H, m), 8.14-8.20 (2H, m), 8.05-8.08 (1H, m), 7.80-7.95 (3H, m), 7.55-7.60 (1H, m), 5.64 (1H, br), 4.08 (2H, s).
