実験手順

A solution of (3-quinoxalin-2-ylphenyl)amine (2.21 g, 0.01 mol) in pyridine (10 mL) was cooled to 0° C. and 2-furoyl chloride (1 mL, 0.01 mol) was added dropwise over 10 min. The reaction mixture was stirred overnight at room temperature, diluted with water (50 mL), and stirred until precipitate formed. The solid was filtered, dried, and recrystallized from toluene to afford N-[3-(quinoxalin-2-yl)phenyl]furan-2-carboxamide (2.4 g, 76%). LCMS calculated for C19H13N3O2 (M+H): 316.10. found 316. 1H-NMR (DMSO-d6, 250 Mhz) δH: 10.45 (1H, s), 9.51 (1H, s), 8.68 (1H, s), 8.22-7.80 (7H, m), 7.61 (1H, m), 7.40 (1H, m), 6.81 (1H, m).
