Versuchsvorschrift

EDC (230 mg, 1.2 mmole) was added to a solution (E)3-(6-aminopyridin-3-yl)acrylic acid (164 mg, 1.0 mmole), 2-(methylaminomethyl)thieno[2,3-b]thiophene (220 mg, 1.2 mmole), HOBt H2O (162 mg, 1.2 mmole), and Et3N (0.35 mL, 2.5 mmole) in dry DMF (5 mL) at RT. After 18 hr the mixture was concentrated. Flash chromatography on silica gel (5% EtOH/EtOAc) gave the title compound (138 mg, 42%) as a tan solid: IH NMR (400 MHz, d6-DMSO) δ 8.15 (d, J=2.0 Hz, 1H), 7.84 (bs,1H), 7.57 (d, J=5.2 Hz, 1H), 7.43 (d,J=15.2 Hz,1H), 7.27 (m, 2H), 6.44 (m, 2H), 4.75 (s, 2H), 3.13(s, 3H); for minor rotomer 8 5.00 (s, 2H), 2.95 (s, 3H); MS (ES) nme 330 (M+H)+.
