Reaction Steps
EDC (230 mg, 1.2 mmole) was added to a solution (E)3-(6-aminopyridin-3-yl)acrylic acid (164 mg, 1.0 mmole), 1-methyl-3-(methylaminomethyl)-1H-indazole (210 mg, 1.2 mmole), HOBt.H2O (162 mg, 1.2 mmole), and Et3N (0.28 mL, 2.0 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 (238 mg, 74%) as a white foam: 1H NMR (400 MHz, CDCl3) δ 8.24 (m, 1 H), 7.90 (m, 1 H), 7.65 (m, 2 H), 7.35 (m, 2 H), 7.09 (m, 1 H), 6.73 (m, 1 H), 6.50 (m, 1 H), 5.04 (s, 2 H), 4.83 (bs, 2 H), 4.04 (s, 3 H), 3.10 (s, 3 H); MS (ES) m/e 322 (M+H)+.
