Reaction Steps
EDC (0.84 g, 4.38 mmole) was added to a solution of 3-(6-aminopyridin-3-yl)acrylic acid (0.72 g, 4.38 mmole), 1-ethyl-2-(methylaminomethyl)-1H-indole (0.75 g, 3.98 mmole), HOBt.H2O (0.59 g, 4.38 mmole) and diisopropylethylamine (1.40 mL, 7.96 mmole) in DMF (30 mL) at RT. The reaction was stirred overnight, then was concentrated in vacuo. The residue was diluted with water and extracted with ethyl acetate. The combined organic extracts were washed with brine and dried over Na2SO4. Flash chromatography on silica gel (5% MeOH/CHCl3) gave the title compound (0.40 g, 30%) as a light tan solid: MS (ES) m/e 335 (M+H)+.
