Versuchsvorschrift

To a solution of (3-quinoxalin-2-ylphenyl)amine (100 mg, 0.452 mmol) and diisopropylethylamine (DIEA, 90 μL, 0.542 mmol) in THF (5 mL), acryloyl chloride (41 μL, 0.497 mmol) was added at room temperature and the reaction mixture was stirred for 24 hrs. Upon diluted with ethyl acetate (25 mL), the organic phase was washed with water (25 mL), dried over MgSO4, filtered and the solvent evaporated in vacuo to afford N-(3-(quinoxalin-2-yl)phenyl)acrylamide (109 mg, 87% yield). LCMS calculated for C17H13N3O (M+H): 276.31. found 276.17. 1H-NMR (DMSO-d6, 400 Mhz) δH: 10.49 (1H, br.), 9.52 (1H, s), 8.60 (1H, m), 8.13-8.16 (2H, m), 8.05-8.08 (1H, m), 7.80-7.95 (3H, m), 7.55-7.60 (1H, m), 6.48-6.58 (1H, dd, J=10 Hz and 16.5 Hz), 6.32 (1H, d, J=16.5 Hz), 5.80 (1H, d, J=10 Hz).
